Another Wheel Fitment Question
 

My very first post! Recently began work on a 1971 Cutlass, and have my eyes on a particular set of wheels. Problem is... I KNOW it is gonna be tight. Here are the wheel specs:

FRONT: 19x9.5 +20 offset (I believe that would be 6" backspacing)
REAR 19x11 +25 offset (7" backspacing?)

I am not opposed to using a small spacer of some sort if necessary, as I have not personally ever had a bad experience with them... but would still prefer not to.

So... can these fit, or am I just TOO far off?

Thanks!
