BudRod, should probably move this to the Driveline Forum but I'll say this..... the torque tube can be pulled out and a rear end up thru 1962 will bolt into the original housing. I used a 1959 pumpkin but the 3.90 rear end was to low for me as I'm running a 700R4 with a V8....so I bought a ring and pinion from Yukon gear that is a 3.38 and it keeps the RPM's down for me.
(when removing the torque tube rear end you have to weld up, or remove the swivels from the vehicle and use some 3" perch blocks to set pinion angle and weld in place....all this is if you change the old tranny out.
There are some 'higher gear" ratio's available but the junk yards where you find them are just about all going out of business. Good luck.....

Good luck

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
