Will 6 lug disc brakes of 73-87 4 x 4 work on 69 conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can I use the rotors off a 4 x 4 front end to go on a 2 wheel drive crossmember from a 73 - 87 truck to maintain the 6 lugs?

I would not think so.4x4 uses totaly different suspention on the front than the 2-wheel drive,4x4 use leaf springs on the front and the 2 wheel drive uses coil springs and a-arms,I'am sure something just would not fit correct,maybe some body with more experiance has more info on it.

I looked in my chevrolet pickup parts interchange manual 1967-1978.
There were no interchanges for 4x4 to 4x2.
I would think that the center of the rotor would be larger on a 4x4 for the locking hubs?
I have read a few post about people wanting to keep 6-lug and have disc brakes but don't recall anybody having that sugestion.

Plus that would be way too easy if you could just swap a few parts and keep 6-lug and get disc rotors

Try it and let us know,I would like to put disc brakes on my wifes truck and be able to keep the wheels that are on it without buying a kit for big$$.

The 2 wheel drive has the bearings and races in the rotor while every 4X4 I have ever worked on (which, admitedly is a very small number) had a 'hat' style rotor that slid over the hub assembly.
