Wheel and tire sizing help please

[lawlorj]

I'm going to pull the trigger on some wheels for my 1968 Camaro very soon. In the wheel and tire database "Jonathan" has the exact wheel and tire dimensions I want to go with, 17x8 4.5" BS 235/45/17 fronts, 17x9 5" BS 275/40/17 rears. That just so happens to be the dimensions of the wheels I want. I made my own measurements on my car and it looks like they will fit. However, I am a bit hesitant to go with that combo because multiple sources are saying that the front and rear backspacing is not correct for a 68. This is making me second guess my measurements. So if there is anyone else running that combo that can chime in it would be greatly appreciated.


Car Specs:
68 Camaro
Front: stock control arms, hotckis 2" lowering springs, C5 brakes, Tall upper ball joints and tie rod ends.
Rear: Currently all stock but going to lowered multi leafs and LS1 brakes on a 8.5" 10 bolt



Thanks!
