Identifying what front disc conversion I have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

footbraker · 02-02-2012, 08:08 AM

1970 c10, 2wd. Someone already changed it to 5 lug and front disc. They did however leave it manual brakes in which I have bought a new master cyl, booster and proportioning valve combo from cpp.

My question is how do I tell of they used 71-72 parts or 73-87 because I need to rebuild the front end and need to know what brake hoses, tie rods, balljoints, rotors, etc to purchase.

If there's a way I can identify what's been used, please let me know.

Thanks

Post some pics,... that will help.
The only way to know for sure is to check the balljoints or outer tie rods.
You might have to take your old ones to the parts store with you.

A quick way to tell is the 67-72's used steel sleeves w/rubber lined screw in bushings for the a-arm pivots. 73-87's used a press-in steel shell w/a much thicker rubber bushing.

But.... the earlier arms can still be combined w/the later spindles & brake hardware. To be sure, the BJ's & TRE's are the way to tell.
