    I swapped my 10-bolt axles for 12-bolts in my 89 blazer. Now it is time to do the rear brakes, and I dont know what to tell the guys at the part house. I have no clue what the axles came out of. They have searched under early 80s c10 4x4 trucks, but no luck. I do have the stamped number (3989541), and the wheel cylinder I think is (519). How can I find the right parts?

    If memory serves me right, 12bolts were mostly in 70's 1/2ton rigs /forums/images/graemlins/thumb.gif

    For a 12 bolt, tell them 76-78ish K5 or K10 and they should be able to find what you need.

    Ill try those years. I wonder if there is a number stamped on the axle that would identify what truck it originated from. Also, does anyone know of a site that has part number cross-references that may help?

    there is a number stamped on the axle, but I couldn't tell you how to read it....as far as part number cross reference, you can try napa i know you can use non-napa numbers, but i don't know if the numbers you mentioned will work there, but its worth a try.

    If you work in Pensacola, call my brother Scott at the Pace & Jackson O'reilly's he'll help you out with what you need. He works most nights and Sundays.
    Best thing to do if you have another ride to the parts store then bring the shoes and drum from one side with you

    Rob, I work in Fort Walton, but live in GB. I just got back from Napa, and I think they found me a match. The only thing in question is it may touch the backing plate. I will find out tonight. Thanks for the connection in case this doesnt work.

    Why dont you just swap the 10 bolt brakes over to the 12 bolt. Take the backing plates off the 10 and swap them on the 12. Its a direct bolt-up.

    To do this, you need to remove the axleshafts, but its no biggie. The best part is that you dont have to remove the parking brake cables from the old backing plates.

    All is good. I decided to tear into my old 10-bolt for the backing plates. It took me most of the day to do the swap, but I am so glad I did. Now I have my original brakes, and my e-brakes are hooked up again. Well worth the trouble
