I have a 63 Valiant with 9" front drums. If I swap in 10" drums from a 66 V8 Dart,
what other parts do I need to go with the big drums?
Spindles, UCA, LCA ball joint?

Then what's the widest tires I can put on 14x5.5 stock rims?

Don't know about the drums, but the widest tire I'd put on a 14 x 5.5" rim is a 205/70 14.

I'm using 195/70 14's on the 14x5.5" rim.

This post answers the ball joint and control arm questions, but what about the spindles?
Will a 66 big drum fit on the same spindle as a 63 small drum?

just did this on my 62-- all you need is the spindle /backing plate assy-- upper/lower --control arms are the same-- you need the stuff between-- brake hose will be different also--
it stops much better!!!!!
9" spindles are smaller than the 10" ones-- -ez swap

Which brake hoses did you use?

ones for 10" brake a bodies

duh

Got my 10" drum brakes, spindles and stuff.
Only broke one bolt.

Now I need three or five 14x5.5 rims.

I'm going to get a front end kit for a 65-72 disc brake car for the HD lower ball joint.

The V8 torsion bars (probably .870 ) should be in good shape - I pulled them back 6 inches and rested the front on a metal crossbar of this cage they sat the car on.
Portland Auto Wrecking - a 66 Dart 270 4-door, all the way in back.

If they were LBP, I have a set of 4 off a '74 Duster you could have for local pickup...

-D.Idiot

I need SBP
Thanks anyway.
I hope to find a 70s sbp car with wheels still on it somewhere in Oregon pick a parts.

The right 10" drum assy I got had a broken stud, but later I found out it had LH threaded studs! Both front drums had LH threads!
I struggled to remove the broken stud - my first time.
It took a day and a half, but I now have new RH studs in the hub and loose drum.


Using a hand drill and a hammer, I center-drilled the head of each stud with a 3/16" bit, then a 1/2" bit, then I used a rotary file bit to grind the hole larger until the ring that was left over from the head came loose.

The whole time I was concerned that I was damaging the hub or drum with my roundabout way of grinding off the heads.

Now I have new studs on what will become my right front wheel, but what about the others?
The right rear studs feel like they're stretching, so they should go.

New RH studs all around would be a nice upgrade and would alleviate somewhat the fear that a wheel will fall off on the freeway.
Although the correct way to do the rear studs would be removing the axle shafts and replacing the studs on the bench, there then would be the fear of an axle shaft coming loose at speed.
