I am brand new to this forum but I must say it is the best, I am getting new rims for my 1977 camaro and I am not very knowledgeable of the fitment. They are C6 ZO6 rims that are 17×8.5 fronts and 18×9.5 rears. Both are +56 offset. The bolt pattern is 5×4.75. Will I need adapters? If so what size up front and what size rear? Thank you so much for all the help and feedback!!
