14BSF rotors

Soooo, brakes need some work on the '88.
The PO installed a 14BSF rear end and a disc conversion. Is there a way to tell what replacement rotors and pads ill need? Haven't had any luck just searching the diameter and bolt pattern of the rotor.

A lot of kits use a rotor from a 70’s 3/4 ton D44 (like a ‘74 K20) other than that it’s just matching parts based on measurements.

I need it 6 lug is the issue, not 8 lug. Its a 6 x 5.5 m14 lug pattern.
Front is the stock 10 bolt w/ with 7/16 lugs on a 6x 5.5

Gotcha, I figured the 14 bsf was the more common 8 lug unit.

A lot of folks have modified 14-SF’s on here and might be able to help identify your parts if you can give a few good detailed quality photos of what ya got.

And welcome aboard !

What does it look like? The GMT900 and GM2kxx 14SF came with discs from the factory.

Most 6 lug disc brake conversions used the gmt400 series front disc.
I had one on my rear 12bolt.
Post a picture of the rotor and I might be able to confirm
