Hi and thanks!
I have stock trailing arms. 18x12 rear wheels and 18X9.5 front. we put Custom Image Corvettes flares on-4" rear and 2" front. They make a 3" front now that would let you go wider in the front which would be bad-ass. The front is a stock 73 front bumper cover an the back is a custom image product. If you have any other questions let me know or just call Custom Image Corvettes and talk to Josh or Jess.
Good luck!
Brent

Hi Brent319,

Big fan of your setup. I am going to have my 77 hopefully looking similar to yours in terms of fitment.

Could you share the specs and mods required to making the tires fit?

Are your flares custom?

Thanks for your help!
