I measured my wheel/bolt pattern and measured 5x127. i get on websites and wheel sale sights and EVERYWHERE tells me something different.

on a 2004, 2 wheel drive, 2 door blazer... what is my wheel bolt pattern?!

 

5 x 4.75 (in inches) or 5 x 120.65 (in mm). It's the same for 1st and 2nd Gen as well as for 2wd and 4wd. The only difference you will have is in backspacing between 2wd and 4wd. Stock 2wd backspacing is 4.5" and stock 4wd backspacing is 6".

 

see, i have not heard that one yet! i have heard that bolt pattern.. but half an inch less in back spacing! UGH! haha stressful
