hello, as you can guess by the title I don't know which wheels will fit (without modification of fenders) on my 77 right now I have 14x7 rally wheels on it and would like to go to a 15x8. I was looking at these Cragar's

Cragar 08/61 S/S Super Sport Chrome Wheels 61815 - Free Shipping on Orders Over $99 at Summit Racing

or some Weld's
Weld Racing Prostar Polished Wheels 96-58278 - Free Shipping on Orders Over $99 at Summit Racing

and other wheels like it. I would like to put a 255 tire on it but I'm not good with the whole offset, and backspace thing being new to the whole car game. any help choosing is greatly appreciated, Thanks!

 

I love the prostars...



255 in the back with a 4.5 backspace on an 8' rim would look and fit great.

 

okay cool thanks for the feedback, probably go with the prostar's

 

275/60-15 on Toque Thrust Ds, 15x8, 4.5 bs on the rear here, but you will be tight and your diff will have to be perfectly centered. 15x6 on the front. Good luck.
