5/8 wheel studs, after market rear axles, billet 1350 trans and Dana yokes....Dana rear bearing support cover, and re-enforce the suspension. chassis connectors, remove dana pinion travel stopper, and find a different way...if still used. And lastly, a spool.....none of this clutch type posi stuff....
For the trans, #1 is the bolt in sprag...then steel drum and other stuff....

Stock planetaries? You need steel. The stock Dana axles will take a lot of abuse. If I'm not mistaken, Jim Pranis had stock Dana axles in his 8 sec 3900 lb '68 hemi charger for a while. Personally, I'd rather see some good aftermarket axles and 5/8" studs. If you do get good axles, don't waste money on 1/2" studs. Go 5/8" and be done. You won't regret it.

Sounds like you're good except for the planetaries.

My main thoughts were about the drive shaft and axles and will upgrade to the steel planets. Currently using 1/2" wheel studs. If i upgrade to 5/8", would that require new wheels as well? No, you should be able to enlarge the stud holes in the wheels slightly for the bigger studs. That's what I did w/ my Centerlines.

Thinking about switching the gear this year from a 4.10 to a 3.73, so if the axles still look good I may just keep them. I did this, and it was night and day for street driving for me in the big Hemi...

My street/strip combo: 3950 lb B body car w/driver, 572 Hemi, 5000 stall ATI converter, Hemi input shaft, billet steel front drum, hub, planetary, super Sprag, 3.5" CM driveshaft, 1350 joints, billet yokes. Dana 60, 4.10 Richmond gears, Detroit Locker, stock 23 spline 1967 axles, 1/2 x 3" DC studs. Caltrac bars, mono leafs and shocks. Car has run a best of 9.85 @ 136mph 1.37 60 ft. I Would switch to 5/8 studs but they won't work with the Cragar S/S wheels I run on the street. Next upgrade will be aftermarket axles since Iv'e been beating on the stock 23 splines for almost 40 years now, but I haven't decided if I want to keep the 23 spline Locker or switch to a 35 spline spool.
