So how close was that fit? welding and moving mounts or no?
Again this MAY be a well known to you guys so please let me know if I am going over redundancy.
Thanks for all the great info.
I just do not want this info to die off as it seems the old school tricks are falling way side . More people want the Old school retro fits and we /me the younger guy likes to know how they use to do the set-ups the way they were done in the day. Pictures etc. would be great.

Jim,
At that time it was the way to go..mounting wasnt a big problem (close measurements, etc. )
Obviously these days the 9" Ford is great, but the pontiac would be a strong " vintage" deal.......
Back in the day, most didn't know that the ponticac rear was even in our Z-11. (axles, redrilled for Chev bolt pattern and chev backing plates and brakes were used.
I recall setting up big truck differentials that had a ring gear support bolt. Brass or bronze insert on the bolt I believe. Used so the ring gear would not walk away from the pinion under heavy load. It worked on big trucks, should work on our small differentials as well.
Sure it'll fit Ray, you might have to open up the rear wheel wells a tad though.:eek:My Massey Ferguson tractor has the ring gear support bolt too but I don't think it will fit under th 60

It was a very common trick to install 30 Spline Mopar spider gears in the stock Posi carrier. Then you could install much stronger 30 spline axles. Here's something else interesting.......I was reading one of my old Super Stock & Drag Illustrated magazine from the mid-Sixities and it had a great Technical article by Bill Jenkins on how to make those early Chevy rear axles survive the rigors of drag racing. It was VERY interesting! Get this........The Grump would drill and tap into a very strategic and thought-out location in the front of the cast iron center section and install a 1/2-20 fine thread bolt with bronze brazing built up on the tip. He would tighten the bolt up against the ring gear itself lightly and then back it off and set it with something like .005 clearance. This along with carrier cap braces and Service Package spider gears was what he used in his '62 409's and even Old Reliable IV, his famous '63 Z-11 car. It'd be interesting to see if that modified center section is still in the car.
