JlMerit,
I have rims here that were stock 16s and I had them widened to 7" with 4" spacing in the back and front, basically zero offset.
By my measurements the later '55-'62 housings are too wide.
Did you run stock wheels under yours with the '57 rear end or would I have to bring the back spacing in?
Thank you
I have enough trucks that I would like to stick with the same wheels.
