I personally think the quality of the wheel is much more important that the overall size. I seriously doubt that 22" wheels will fit in the wheel well of a G35 coupe. I would check out the Nissan Tires, Wheels, Brakes and Suspension section at
Yes it should work , Get a good look at both frames and I think they will work the 1940 ford is my favorite car ever made and I have seen some sweet rides, hope this helps.
I always thought the front end of the coupe and roadsters were the same. All those I have seen are a 4 piece unit. 2 peices per side. Are they not the same from the cowl to the grille. Beautiful car either way
