Hmmm, not what I was hoping to learn.... but that is the way it goes with the old truck I guess!
I actually already have modern 6 bolt 15" rims, so I am not interested in changing the front to 5 bolt. Plus from what I can see 6 bolt is becoming the norm on the newer chevy trucks from the mid size on up, so I suspect there are even more rims to choose from now?
If anyone has done the 6 bolt disc brake conversion, please let me know!!!
