Rear drum 6 to 5 lug

[ARTISTIC]

Tried a search and didnt find something related.

Im switching out my 6 lug axles for 5.

I intend to get the complete front and rear disc setup and suspension rebuild this spring so in the meantime to keep my truck on the road I have to get my 6 lug drums to 5.

Are the 5 lug 1/2 ton drums the same dia. and depth as the 3/4 ton?

Hoping I can just pickup a set of new drums to tide me over until this summer and not have to replace all the guts as well.

What width are the drums/shoes? OE 5-lug truck drums are the 2" width. If they're wider than that, try OE drums off of a mid 70's burb (HD brakes had 2.75" width).

Im going to either get my truck someplace dry this weekend or just crawl around in the snow and measure them. There isnt a business up here that has anything of this era in stock so I have to ship everything so right on the first try is my goal.

take the rear axles to a machine shop, have the centers turned down to accept a 71 c10 rear drum (5 hole),,cut off the 6 studs, and redrill the axle for 5X5 bolt pattern, I changed the front end out with a 91 suburban and got disc brakes and 5x5 lugs on the front for $500.00 The machine work on the rear axles cost $80.00 .... The alternative is go to CPP and others and they sell axle conversion kits with new axles, drums, etc. Kieth

Here is a link that shows the modified rear axle hubs on my 66 gmc, if you will look thru the whole gallery you will also see what it took to change out the front crossmember from the 91 burb to get disc brakes and 5 axle hubs.
