what parts would i need for a 5 lug swap

[pissonNOS]

right now im 6 lug front and rear the truck is a 69 gmc lwb with a coil spring rearend, i bought the ece 6 lug dropspindle disc brake kit for the front so now what im wondering is would the 5 lug rotors be a direct swap for the front or do i have to do something else?? and as far as the rear could i just get 5 lug axles out of the same year rearend or what do you guys suggest? im mostly doing this for wheel choice.

You'll likely need the correct rotors for the spindles 'year model': pre-73 (71-72) or post-73. You can prob call the manufacturer of the spindles to determine what year rotors to purchase.

The rear is different. Longer 5-lug axles will physically fit into the shorter 69 rear housing but you'll have to re-configure the brake drums/backing plates. The better option is to replace those 38yr old axles w/some new ones w/the correct 5x5 pattern. ECE & Moser are 2 of the first choices I would look into. New axles that are 30% stronger than stock & have zero wear @ the bearing location is the better option IMO. Then all you do is add 71-72 drums & call it a day.

I've done this on an ECE kit. Just remove the 6 lug rotors and replace them with 71 and newer rotors.

They reuse the same bearings, seals and brakes.

No mods at all.

ok thats what i was hoping i could do on the rotors, did u have to get the rotors from ECE or is this a parts store item i can get locally?

Yep, parts store or your favorite pre-owned auto parts yard.

Call Moser, tell 'em what year the rear end is & they do the rest. Add some 71-72 drums & you're done.

if i wanted to use the 72 axles in my 68 rear, what drums would i need to look for at the parts place?

72 axles are longer than the earlier housing which requires specific offset backing plates & the right drums. I believe people use the HD 2.75" drum parts but I've never confirmed it. I've also heard of spacing the backing plate.

When I did mine I considered the used parts route until I opened up the rear w/the replacement axles & noticed the bearing wear that existed. I reconsidered & went w/Mosers stuff.
