Disc brake conversion for '66
#17
I just recently decided to convert my 66 f 100 to disc brakes. I found a 79 f 100 to pull my parts from but the truck was wrecked so I can only pull spindles will I be able to change kin pins. And keep the 66 I beams. I read one forum that said NoProblem. 1 that said different size king pin would not work. Appreciative of any help.

I paid $800 for a 75 100 with a 390/3spd, ps, pdb, and a bunch of new parts.
The PO had plans to do a "restore" but got fed up and sold it all.
I sold the new fuel tank, fuel lines, and Holly 750 for $250 and the carcass for $200 after I pulled the engine, tranny, PS, and PDB. I also got a new uninstalled LMC dual exhaust system.
BTW: LMC is the last place I would buy a F100 exhaust system. I paid $75 to have it installed, the shop had to do a bunch of cutting and welding to make it fit. There's no way I could have done that in the driveway.
So parts truck are out there, you just have to spend hours looking and be patient.

Kirby, You can connect it all up as one piece. I parked the 76 donor beside my 66, dropped the I-Beam set slid it under the 66 bolted it all up and drove it away.
The king pins are a different size that need a little work to make work.
It has been a few years now, but I sold my donor parts for more than I paid for the truck.

I used a 79 F100 to get the disc brakes for one of our 66 F100. I used a 1979 king pin set as the pins are a bit longer so you have more kingpin in contact with the spindle. The 66 king pins will work, but have less area of contact (yes, I put one side together twice to compare 66 vs 79 king pins)

We jacked her up this weekend to change oil and service. We greased the kingpins, u-joints, adjusted parking brake, checked for play in suspension and wheel bearings, etc.; everything was in tip-top shape. Maybe I just got lucky, but all seems to work just fine. Maybe I should check the part #s on the I beams and spindles to confirm they match a 66 and 79, respectively (are would they not really be part #s, but casting or machining #s?).
