I know less about 64 than 65 but I think this is it . The lug wrench is wrong in pic Should have short neck. Someone will confirm i'm sure. Don

64 jack stalk is T shaped in profile. Ill try to snap a picture of one for you.

Andre is correct

John V. · 04-28-2011, 08:47 PM

Andre, I used to think the '64 Tempest only used the T shaped rack. But several years ago, OMT offered up what he believed to be the original jack from his '64 Fremont GTO that he bought new (in March IIRC) and it was the keystone shaped rack.

In addition, the '66 MPC offers a possible clue that both styles were likely used, possibly a vendor difference and/or possibly a Plant difference.

Only one jack assembly was listed and doesn't identify the rack shape.

But 2 different bases are listed for the '64 Tempest application.

The p/ns are sequential and clearly '64 vintage, the base for the T shaped rack is 9774441 and the keystone rack base is 9774442. Both are the 6x6 size. Can't imagine why they serviced both unless they actually used both in production.

Going by memory, but I think they list usage of both bases for '65 and '66 too.

I've noticed that some of the bases say A which I assume is for A body, and some say B which is for fullsize, but I also have one that says A B. I think there is also 2 T profiles. Now I have to drag out all my jacks and take pictures this weekend.

The following pictures are of a jack from a 64 Catalina. Note the sticker on the bumper hook.

Wonder if anybody has an early unrevised '64 MPC to check the '64 Tempest jack assembly p/n listing?

In the '66 MPC, the jack assembly is p/n 9775191. Too bad it doesn't identify the rack type.

Chad, I'm wondering if the jack you pulled from the '64 Cat is really correct for the '64.

The MPC shows that the Adapter for '64 was for the Front Bumper.

In '65 (and '66), the big car Adapter was for the Rear Bumper.

Based on the label, I'm thinking that it is a '65 (or '66) jack unless the MPC description is wrong?

Any '64 big car owners know the answer?

There is a 3rd Base listed in the MPC, '64-'66 All (which doesn't always signify that it applies to the Tempest). This one is p/n 9775045 (clearly originated for '64).

It shows it is a 6-1/2x7-1/2 Base for use with a square shape jack. The p/n of the square shape jack assembly is not given in the description for this Base.

A couple of other 6x6 Bases for square shape jack assemblies are listed and identify the p/ns for the corresponding jack assemblies. These are pre '64 vintage p/ns and only one of the identified jack assemblies is listed for service (535086 for '60-'63 big car applications). But the associated 6x6 Base (p/n 533964) shows the application as '59-'66 P/8. That would suggest that the '64 big car could have used either a square shape jack or a keystone shape jack. No indication that the T shape jack was used in the '64 big car according to the Base listings, but I wouldn't doubt that was also possible.

I bought a used Chevy jack mainly for the T shape rack. It has a non-removable adapter assembled to the ratchet. The adapter is stamped "CHEVELLE 1965" and under that "CHEVY II 1965". The 6x6 Base is marked with an A.

There was a jack in my car when I got it, too clean to have been original. Keystone shape rack, rectangular Base stamped with a U. The ratchet is correct looking for a Pontiac with the rubber pad and tang for the bumper slot. I have no idea where it came from.

The Resto Guide claims the T rack was used in '64. But it doesn't account for the '64 9774442 Base for keystone shape jacks. It acknowledges the use of a keystone shape jack (Base p/n 9783393) and the square shape jack (Base p/n 9781295) for the '65-'67 even though p/n 9783393 would not have been issued until well into the '65 Model Year whereas the '66 MPC seems to suggest the '65 would have used Base p/n 9774442 with a keystone shape jack assembly.

And no mention of the use of the T shape jack for '66, even though a '66 Tempest application of the Base p/n 9774441 is shown in the '66 MPC.

The Resto Guide seems to have relied on a later MPC for its conclusions.

I don't know if there will ever be a resolution. I like the "look" of the T shape rack because I think it looks more "vintage". But I'm not convinced it was the only jack style installed in the '64 Tempest as O.E. from the various factories at all points during the model year.

I believe more than one style is correct but wouldn't be surprised if the GTOAA only acknowledges the T rack because of what the Resto Guide shows.

What has everybody else seen?

I had a 64 Grand Prix that had the same jack. 8LUG, your thoughts?

Okay, let me see if I can outline this without causing confusion. I am going to show 4 '64 jacks that I have. 2 are longer and fullsize and a one has the adapter, and the other does not. The other major difference is one jack has a square base, and the other has a rectangular base, and the cross sections appear to be different, but I have to review that once again.

The other 2 jacks are shorter, and both are the same length. What is really distinct about them is that they have a different cross section shape. One style is a T, the other is a Y, like the fullsize jacks. I have one more jack that is T or Y style that is in my '64 Lemans convertible that is all original though tired, but I didn't want to get dirty getting it out.

This post shows my first fullsize jack. The square base is the one that says A

Andre · 04-29-2011, 06:21 PM

Jack #2. Another fullsize jack- Y cross section. Rectangular base A-B on the base. This one still has the bumper hook.

Andre · 06:39 PM

Jack # 3 A complete '64 Lemans/Tempest jack. It has a small stubby lug wrench with a curve, but I forgot to take a picture of it. The base says A and is square. Note the cross section is a T, not a Y

Andre · 04-29-2011, 06:35 PM

Jack 4- This one is the same length as jack 3, but I don't have a base for it. The cross section is a Y, like the 2 full size jacks.

64woodwheel · 04-30-2011, 01:24 PM

This is a complete original everything jack from my 64 Lemans, 17K, second owner, June '64 Pontiac build. The black marks on the blue paint are from the original US Royal spare.

8LUG · 04-30-2011, 02:24 PM

The jack Chad has a picture of is for 64 large car. in the MPB, the adapter is for the rear bumper but it states front which is wrong. NO ADAPTER WAS USED ON FRONT BUMPER OF 64 LARGE CARS. My guess on the A body jacks, 3 vendors for jack assembly all one part number and the 3 bases had there own part number base w/T SHAPE 6X6-9774441 base w/KEYSTONE 6X6 -9774442 BASE W/SQUARE SHAPE 6-1/2X 7-1/2 9775045 IN 1964

Andre · 04-30-2011, 03:06 PM

I agree with the one that 64woodwheel shows as being the 64 A body jack. That one matches my loose one including the curved lug wrench. I also checked it against the one in my '64 Lemans, and it is the same as that one. The stalk length of the ones I have that I consider to be fullsize are significantly longer than the A body ones.
