The 70 Duster......

CarCrazyGuy - Kudos to you for your patience with this project :angel7:

Those axles do look scary ! There's no meat next to those studs ( double-entendre ? =P~ ) !!
Perhaps you could grind some studs down to their ribbed part and slam 'em in the gaps ( or pop the new studs out , slam the old-style studs in their respective holes , grind 'em down smooth , and then pop the new studs in their spots ) ?

For a cruiser , I'd stick with a fairly mild 360 ; just my opinion , for what that's worth .
I'd put my coin towards building a beefed-up 727 or even a Keisler 4 speed auto ; again , my opinion 8).

I don't think you could go wrong with either J5 or J6 green :happy10:
