bolt patern and back spacing

[Jason Wiechec]

I finally got a truck. it's an 85 silverrado with a 350/th350 combo. I want to run  AR torq trust m rims in black i want to do 18's in front 20's back. I have a couple questions.
1. what is the bolt pattern and back spacing for my truck?
2. The only size 18's i can find in those rims are 18x9 will they fit under the front of the truck?

If you have a discount tire or america's tire company (same corp) You should be able to get them through them.

A similar wheel is the Boss 338 or Coy's C5, usually less expensive than the torq thrusts.

will i have to modify anything for this set up to fit properly

The front should clear just fine, so should the rear. Worst you may have to do is roll the lip on the fender and quarters.
