So my son just got a very nice original 68 Fury3 with manual drum brakes. Who makes a nice inexpensive front disc conversion for C body? Does not need to go to power, would just like to ditch the front drums and retain same spindles if possible. No high end willwood race type stuff, just a 318 Saturday night cruiser.

https://scarebird.com/index.php?route=product/product&path=64&product_id=255this is the only conversion I am aware of. it would honestly be better if you could find the 70-2 or the 73 spindles. vans use the rotors for the 73. so they are still availble new. dr diff I think makes the adapter bearings for the 70-2 spindles to use the 73 rotors.

I have a couple sets of the '73 disc knuckles sitting on the shelf. I took them to a swap meet last year but they didn't sell. There's the solution right there. All the parts to complete the job are at your favorite parts store. Those spindles will fit your drum spindle ball joints. Kevin

The F M J parts will fit A B E bodies but not C.
Check the Mopar Action disc conversion article.

Definitely will buy a set if you’re willing to ship, I coincidentally also have a ‘68 Fury III and want to ditch the front drums. My car has a hot 440 in it and the brakes are marginal at best. Thanks!

Check the Mopar Action disc conversion article. The MA article has lots of issues in it.

Check the Mopar Action disc conversion article. Or go here, get your refreshments ready, it's a long read. Somewhere in there somebody called out the bearings and other part numbers you need: https://www.forcbodiesonly.com/mopar-forum/threads/fuselage-drums-to-disc-brake-conversion.23988/or here: https://www.hotrod.com/articles/mopp-1107-c-body-disc-brake-conversion/#photo-01 Short story, buy the spindles, pick up the rest at the store. The hard part, you need the specific PDB to get adequate boost. Some guys claim to have gotten good results with the drum booster. Factories are CHEAP, they don't make changes lightly, go with the right parts. No matter how expensive you go, it's still cheaper than an accident, probably cheaper than your deductible.

Check the Mopar Action disc conversion article. The MA article has lots of issues in it. No issues . . . speaking real world experience . . . . and at time, these were dime a dozen at wrecking yards . . . cheap replacement parts (calipers/pads, etc), and you go with the bigger caliper bracket from "B" body, you can then go with bigger rotor . . . honestly, no issue in over 10k miles ! . . . and my car is non power brake car, no issue with a "tough pedal", very responsive and easy to use. I would talk to Dr. Diff and check his website . . .

That's why they fit then. A 64 is not a Cbody. Cbody didn't start until 1965. Any tricks required to use the FMJ on that 64? Kevin

Kevin Call it what you want, it was a Cbody for all intents and purposes, had to trim the tie rod length to get the toe in spec, other than that nothing serious. Spindle heights were the same.

Spindle heights were the same. i as well have real world experience using the FMJ spindle, probably close to 40 vehicles, and i did a 64 300 in the mix. as sniper said, the only issue [if you could really call it that] was trimming the tierod length. i remember when i joined here, there was a big flap about using the tall spindle and "over extending" the upper ball joint. i proved to myself that was an impossibility by moving the suspension through it's entire range.

And IIRC, Ebooger claimed it was a possibility, he didn't guarantee it would cause problems.
And a 64 really isn't a C body, not many chassis parts swap.
As for trimming tie rods to get toe in spec, you wouldn't have to do that on an A B E body because the steering arm is part of the ball joint, not the spindle.

To quote Allpar "The C body dates from 1960, but was not officially named until 1965." https://www.allpar.com/threads/rear-wheel-drive-mopar-bodies-1957-2017.228756/#post-1085222854On both the FMJ and the 64 C body the steering arm bolts to the spindle and the LBJ stud mounts to the steering arms. Right now I cannot remember which source I used for the steering arms after the conversion. I think the FMJ donor's. I did the swap back in 94 so the memory is dim these days.

All the parts to complete the job are at your favorite parts store. Those spindles will fit your drum spindle ball joints. Kevin Question, are lower balljoints available anymore? About 20 yrs ago when I replaced them on a '71 Chrysler I had, I was told they weren't being made anymore and I had gotten the last pair available (in this area at least). Just curious.
