1972 6-Lug to 5-Lug Conversion question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

D-n-Tyke · Yesterday, 02:11 AM

Looking at possibly converting a 1971/72 C10 from 6-Lug to 5-Lug. I was wondering, for the front can you just swap out the 71/72 6-Lug rotors and bearings for 73-87 5-Lug rotors and bearings. Then using the 71/72 brackets and calipers.

Or do you HAVE to swap over all the 73-87 brake components?

You have a 6 lug on a 1971-72 2wd C10? That doesn't sound right. I'm usually wrong when I pipe up, but if it is a 6 lug you might have a 1970 or older.

For a 1970 or older you actually want a 71-72 front end, that's what I am currently looking for. I think a 73 up will work with mods, but 71-72 would be ideal.

Oh man.... I need to open my eyes better. Truck I am looking at is actually a C20 with 8 lugs. So I guess my question is kind of a moot point now.

I think the 71-72 to 73-87 eight lug disk brake conversion is actually easier than previous topic: so that might be good news. I'll let someone with more knowledge add to this.

If it’s a 72 it’s got disc brakes already .

Subbing here. I wouldn't mind learning about converting a 8 lug to disc myself
