I’m trying to plan my wheel/tire combo.
This will possibly be going on a 71 gmc C1500. It’s got the 5x5 lug pattern and no modifications to the suspension. Eventually I’d like to do a 4/6 drop, add some sway bars and perhaps relocate shock mounts. The wheels I’m considering have the following specs. Size: 15x8 | Bolt Pattern: 5x5 | Offset: -19mm | Center Bore: 83.1mm | Backspacing: 3.75. The tires are not the immediate concern yet.
Does anyone see a problem?
I did read the 15 inch wheel thread but no post had all of the wheel specs including back space, offset and bore.
Thank you.

Jeff
