My First Mopar- 1966 Barracuda project

I’ve just gone back through all the pages in this thread and noticed a wheel spacer on the front hub , looks like 1” . Did you have to run them on all locations ?

I running Mopar rallies 15x7 all around until I change the rear axle to my 8 1/4” then I’ll run a 15x8 on the rear with 235 60R15 all around . I hope the 8” rims fit .
