Here's my freshly painted 1971 2wd blazer rolling on 338's with a 1" rotor in the front... A big thanks goes out to Lolife99 for informing us on the 1" rotors!!!!
I purchased a set of belltech's 3" drop spindles for 1" rotors and it fits great.
My sizes are 20x8.5 in front and 20x10 in rear..
I upgraded all the ball joints and tie rods to the 73-87 also with a ART front end bag kit and ART arms.. ( cool ride )
I ended up getting a rear coolride kit also... very nice stuff wirth the $$ IMO..
Here's a couple of Now and before tear down pics..
