I have a 97 blazer and my cousin has 86 monte ss rims ive been wondering if id be able to put them on I don't know the patterns for montes any help would be appreciated

 

The bolt pattern is fine. They are 5x4.75 just like the Blaze. I would be more worried about the backspacing. It looks like the '86 SS wheels had 3.75 inches of backspacing which means they will stick out quite a bit. Are you lifted at all? You would probably be rubbing fender.

 

planned on doing a 2 inch shackle and t bar crank and eventually 2 inch pa body lift

 

What size tire are you planning to run? Like tibbs said your issue will likely be the rubbing on the back of the fender and possibly the front valence depending on tire size.

 

31 or 32 and I don't have a front valance
