6 Lug chevy p/u

I have a 72 chevy p/u. It has 5 lug wheels. I am thinking about late model 6 lug wheels, is there a 6 lug disk brake rotor from chevy for it? or are they drum brakes only . I was thinking about getting a late model rear with 6 lugs, and changing the front rotors to 6 lug so I can run stock chevy 6 lug aluminum wheels. would this be a good idea? I like some of the stock 6 lug aluminum wheels. And I could change the rear axel to a factory limited slip in the 4-10 gear range out of a four wheel drive. As always THANKS for any advise.

the rear is easy 67-70 are 6 lug
the front you'll need the 6 lug optional disc brakes spindle on out.
it be easier to use the 5 lug pattern. as the 71-72 came with disc brakes..

For the front, using the stock spindles, your only option is aftermarket (ECE, CPP, etc.) front rotors as GM never made a 6 lug rotor for the '71-'87 spindle. For the rear, use any '63-'70 rear axle (I am assuming you have coil spring rear suspension) as this will be a direct bolt in with 6 lug.

On thing to keep in mind, the later 6 lug wheels typically have a smaller center bore and a lot of late model wheels will not fit the aftermarket 6 lug rotors due to the larger hubs. Same with the rear axle, the step sticking out of the drum (axle hub) is larger than later models.

Another thing, many later model wheels have a large positive offset that will cause the wheels to be pulled into the wheel wells and create clearance issues. Later model trucks had the track centerlines wider than early trucks.

I have been in the 60-72 truck world for almost 20 years and it's not too common to see people going from 5 lug to 6. Typically it's the other way around. Now this is a trick method of using factory GM rotors/parts but it takes a little parts swapping. If you use '63-'87 3/4 ton lower A arms, you can use spindles from a '92-'98 C1500 or Light Duty C2500 (these are 6 lug spindles) and use the similar year ball joints and either the factory 5 or 6 lug rotors. You use the similar years outer tie rod and an adapter adjuster that will allow it to connect to the earlier inner tie rod. This is about the only way to use factory parts to do this.

Good luck.
