offset for 20" rims on factory susp.
 

Hey guys..ive seen a lot of trucks with chrome 20's with factory susp, and just want to know what the offset of the rims were or if spacers were used. I have a 69 c10 and tried to put 03 1500 rims, but would not fit. Lug pattern was right, but rim was hitting susp. please help me out, thanks...if anyone has some wheels...please post em..i'm looking for a set..Thanks!
