An accurate 8 3/4" rear axle width list

Spline? Axle splines? Pretty sure all the common year non race are the same. I forget the count to tell ya the truth.

As for gears it all depends what you are doing. Stock 318 and just a driver I'd say 2:76-2:94.

More then stock 318 and just around town maybe a 3:23-3:55. All depends on your combo and intended use.

i wasn’t sure if I’ll need a 28 or 30 spline and didn’t know if I needed a certain year for upgrading the rear end since 63 Valiant didn’t come with a 8.75.

My 318 build is going to have budget high performance, So would you recommend the 3.55 gears because I would like to drive to various car shows as well as around town.
Thanks for your help.
