6 lug disc to 5 lug disc

[theyammieguy]

I have disc up front in a 6 bolt pattern, is it as easy as buying a 5 lug rotor to do the swap? If so which rotor would I need?

[d10s69c10]

72 i believe was 5 lug would be the simplest.

i got a 75 front end on mine somehow. just came home that way.

Pretty sure mine is the stock crossmember but have no idea what brand conversion kit was used.

i would think so, you could pull a rotor and take it with you to the parts store and have them mic the 6 lug vs. 5 lug, if the same inner diameter you should be able to bolt up.

if you were not several hours away, i would let you test fit some stock rotors i have in the garage.

I might head to the junkyard on saturday and take a few measurements.

Thanks for the offer.

yes 71/72 were disk brakes, just did a 72 xmember swap a couple weekends back. the only thing i would be concerned with would be the inner diameter to make sure they both use the same size bearings... good luck.

Used the whole front crossmember on mine...its out a a 87. I used the power steering out of that truck too.

All of the 6 lug disc conversions I've ever messed with used interchangable rotors with 5 lug. Same bearings, same seals, same calipers and pads.

My 72 short bed actually has 68 model disc brake spindles from ECE. I sold the 6 lug rotors on this board and replaced them with parts store 5 lug rotors off a 73 model.

[my67chevytruck]

thanks TX for clarifying this . I was pretty sure they would but errored on the side of caution.

I would be intrested in your six lug stuff. I have a comolaet 5 lug 72 front end

What all was involved with the swap? I have a 87 crossmember and rear diff coming to me from Austin.

Ok, what is a comolaet front end?

Tell you what, I have a 87 front end coming from Austin. You come down to Houston and help me do the swap and you have everything you want off my old crossmember.

I think he meant to type Complete 5 lug front end

Only thing I don't have is an engine hoist.

I'm the one who bought your 6 lug rotors, they've been working very well for the past couple years. My truck had a complete stock 71 5 lug suspension under it, but because I couldn't find a 5 lug rear for a reasonable price, and I wanted to run rallys anyway, I bought the rotors instead. It was a straight swap. Bearings, calipers, etc all fit the same.
