11 5/32" x 2 3/4" HD brakes on C-10?

Hey Guys,

Did the 2 3/4" wide HD brakes ever come stock on a '70 C-10?

I currently have the standard 11" diameter by 2" wide drums all around & want to put 6-lug discs up front & 2 3/4" drums in the rear.

Does anyone have any experience with this?

Thanks,

John O.

I plan on upgrading my rear drums eventually also, here's a link to what I think you're talking about.

My only question after re-reading the post I linked is will the stock wheel cylinders work? I may replace mine when upgrading and am wondering if I would also need the wheel cylinders from the later model brakes.

Any input Tx Firefighter?
