I am trying to change my six lug rear drum into a 5 lug and i was wondering if i could just simply change just the drum part were the lugs are located?

MARRY CHRISTMAS!!

the lugs are on the axle itself. you would have to swap them or redrill for 5 lugs and use 5 lug drums. pretty sure thats right. can anyone confirm?

Correct indeed, Grasshopper.

Have to do a complete rear swap or replace the axles. here is a fairly priced kit from CPP

thats the thing the lugs are not on the axle they are on the drum part. if i take the drum of the lugs come off.

Something doesn't sound right here. On a C10 the wheel studs are pressed into the axle flange. Is the axle and all coming out with the drum? You can convert to 5 lug, but you first have to change out the axles to aftermarket 5 lug axles. Then you can upgrade to the larger 5 lug brakes by changint the backing plates, drums and all internals. This should be able to be found at a local wrecking yard.

Its not that simple....this kit is splined to work with the OEM rearend. Even if you go to a shop they still respline your originals and or fit adaptor style backing plats. Its almost better to do it correctly and just get a new rearend off a donor...this way you can get better freeway gearing too! BUT the kit is descent too.

what model rear do you have? it sounds like its not a 12 bolt.

Me thinks we're havin' terminology issues here
The brake drum is just the the "capped tube" about 11 by 2 inches on the end of the drive axle. the drive axle holds the wheel studs (another missname because they are spline cap srews) Any production 1/2 ton rear drive axle assembly (also shortened to axle to add to the confusion) that I, and I would guess most of us, have seen have the wheel stud drawn thru the axle shaft's flanged end.
6 bolts were mentioned which on a 66 chev or canadian GMC should indicate a semi floating GM corporate 12bolt (named for the 12 bolt cover pan)
Does this put us all on the same page???
