Ford 9" 3.062 pumpkin and 35 spline axles
I picked up a 9" housing and 35 spline axles a few years ago in case I needed for a 2nd gen.
Just got a new never used MW aluminum 3rd member housing for $200-guy had circle track cars and passed away. Bearing saddles though are 3.062. They make bearings and a spool for that sized bearing but is it too thin and potential for breaking? No lockers until you step up to the 3.250 saddle pumpkin.

I ran that spool in my 2nd gen in the 10s for many seasons and never had any issues. Car weighed around 3200 lbs and would run 10.30 at 133 with a big wheelie off the line. Ran 29.5x10.5 Hoosier radials so would dead hook every time.
MW spools are really good quality.

I ran a locker with 3.062 bearing. Its stock size.

I think the Lockers for that size only go to 31 spline and I already have 35 spline axles.
Pushing my car with a spool around the shop is sure a pain but it will probably just be for track use so a spoll will work.

I'll check but I think all the 35 spline Lockers are for the 3.250 bearing.
Even with a spool I was wondering if the 35 spline in the 3.062 was too thin and would break.

So researching this a little more MW has a spool for this bearing size. They saw good for 800HP, but theirs is for a "45 degree pressure angle spline" which is what their axles are cut with. Moser says their 35 spline axles are 30 degrees, Allstar makes a spool but uses a "35 degree pressure angle".
And to throw another question mark in all these angles I asked the Moser tech about the 33 spline 12 bolt axles and spool I got form them years ago in the Camaro. They said those are 45 degrees and why when I asked at that time if I swapped to a Posi or Locker if I could use the same axles they said probably not!

Allstar spool came in . Man I can see why for big HP you want a 3.250 bearing for the spool. It is only 0.152 thick at the thinnest part of the spool!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
