H/D brakes (1.25 rotor)

I have 73-87 drop spindles for the 1.25 rotors. I just went to purchase rotors and calipers at rockauto.com and none of the descriptions say if they are standard duty or heavy duty. Has anybody purchased from there before and can tell me what to buy? I would prefer to buy from rockauto because it it ALOT cheaper even with shipping, but if anybody knows part numbers for either Autozone, Advance, or NAPA, I would appreciate that too.

Thanks,
josh

NAPA part number for 1.25" rotors is 85537

I purchased mine last summer, $148 for both total. They were the top of the line.

Re: H/D brakes (1.25 rotor)

Not to get to far off topic

My 86K10, has the 1" rotor.....standard brakes.

How do upgrade my 86K10 to the heavy duty brakes?
Can I upgrade both front and rear?
If someone has a list of the stuff required, and what to do that would be great. I have a doner K10 and I am rebuilding both axles with 3.23 gears, and would like to do the brakes at the same time

Thanks
Duro
