Transmission Crossmember Height
I got ahead of myself in boxing my frame and sectioned my crossmember before I measured it's height to the frame.
I'd like to know the height of the bottom/center of the crossmember, below the trans mount, in relation to a straight line between the bottom of both frame rails. Hopefully one of you guys can conveniently take the measurement,,,,,

I have a convertible cross-member where I can get you close on the heights.
I will measure it up in the next couple of days and post the info. Tom v.

When I put the transmission cross-member on a flat surface.
(No rubber biscuits on the ends and the cross-member flipped upside down) A caliper inserted in the Trans Mount holes and measuring from the flat surface to the cross-member bottom surface (now the top most height where the trans mount bolts go thru) measured 2.850" vs the ends of the trans cross-member. Hope that helps. Tom V.

Thanks Tom, it appears that the verts CM is configured differently at the ends since it doesnt lay on the frame rails.
How much higher are the ends vs the rails?

Here is a link to some frame pictures from another website.
I am afraid that I can't help you out as the frames are different where the trans cross-members are mounted. http://www.squidsfabshop.com/gtoframe/gtoframe.html In picture #7 you can see that the Convertible/Heavy duty frame (Boxed) locates the trans mission cross-member "pad" at approximately the same height as the hardtop frame. The isolator used in the convertible frame is .375" thick, then the cross-member thickness (.125") then the upper half of the rubber isolator, .375" thick, and finally the retaining bracket that fits over the isolator and holds the cross-member in the correct location. So I would say that my dimensions need to be offset by the .375" isolator height. Tom V.

Thanks again Tom, so I would deduct the .375 from your 3.85?

Anyone have a new or previously functional crossmember laying around?
If you could measure the height of the ends when it is layed flat, I believe that would be the answer.

You need an actual Hardtop/Coupe cross-member to do an accurate measurement like I did on the convertible piece I have. It would be a guess on the actual dimension from my part, based on a picture, mrtonegto.

Totally agree with a roofed car xmember and your method Tom.

Measurement
Let's give it another try with Christmas spirit!
Looking for the height of the ends with a Xmember placed on a flat surface as shown:

Since it is Thanksgiving Day, tomorrow, I will remeasure my crossmember the way you have it positioned and give you my end measurements.

Just wanted to say hello. Long time no see. Are you still building that 65 burgundy coupe? I still have my 65 coupe if you need measurements. I live near Greer now. cell # 704 491 6445.
