The Stovebolt Site Forums The Parking Lot '60-'66 Trucks 1966 GMC Disk Brake Conversion

Does anyone have experience using the disk brake conversion kits from LMC Truck. I would like to convert the front brakes from drum to disk on my 66.
truck is a 1966 GMC Fleetside, 351 V6, 2wd, manual 4 speed trans.

I'm pretty sure the ball joints are larger than Chevy in that year model so Chevy spindles wouldn't work.
Call Them up and ask. After all that's what they are in " bidness" for.
I would think that the kit would have to be GMC specific.
Good luck.

the easiest cheapest way. is to do a crossmember swap and put the entire front suspension from a 73 & newer truck under it. its almost a bolt in. and you can also bolt the later rear end to the GMC rear leaf springs. you will then have 5 lug wheels and a greater selection of rear gear ratios.

What Wolf is talking about is what I did. Power steering, disc brakes, bigger and better brakes in the rear, and it was almost too easy to do. Riding and guiding like I've got some sense now.

Thanks for the input, looking at picking up an 82 Scottsdale 2wd. will probably do an engine trans conversion as well.

If it were me, I would shy away from a kit. I just did this conversion on my '65 c20, and bought kits for the upgrade, and ended up not using an easy 90% of the kits. The kits either came with very low quality parts, or parts that didn't fit or wouldn't work period. I would recommend sourcing parts from a donor truck from the '73 to 87' range. You'll be much happier. You'll need to re-use your control arms, and have the ball joints pressed in the lowers, and replace the uppers with the bolt-in kind, then it's just swapping things out. It's worth it though. If you have any questions, let me know and I'll answer the best I can.
