[61apachespeed]

anyone runing disc brakes for 60-62??? if so what wheels are you runing?? whats the offset on the wheels?? trying to find out that offset i need to clear disc i have the drop spindles and disc brake kit from ccp.

Is your disc brake kit 5 or 6 lug, and is it fitted to the original torsion bar suspension or a later coil spring front end?

[61apachespeed]

its 6 lug and still torsion bar. i tryed to talk to ccp and they give me the run around

i have a few diff't sets of wheels i have a set of smoothie with a 4 1/4 offset and the stock 15 x 6 wheels and i have a set of rally wheels of a 67.

I believe you won't be able to use any 6 hole wheels that were originally for drum brake trucks. They will have to be either aftermarket wheels or OEM's that were originally on '71 and newer 6 lug applications. I would think that a standard backspacing for a given width of wheel should clear the calipers.

thank you. i still a little lost. on this part. (I would think that a standard backspacing for a given width of wheel should clear the calipers) what is a standard backspacing? are you talking about a spacer on the rotor??? sorry this is all new to me

Post #6 on the following thread explains the interference problem with drum brake wheels on disc brake applications:

And the following link shows a line drawing in the center of the page illustrating a drum brake rim on the left and a disc brake rim on the right. The wheel on the left is demonstrating a reversed rim, but to understand the stock configuration - as drawn, the back of each wheel is facing each other. The tapered shape that causes the interference is obvious on the left wheel :

Just out of curiosity, does anyone know if discs will clear vintage 5-slot 6-lug aluminum wheels?

What I meant is that the standard backspacing of a wheel is going to be different for a given width. For example, a 7" wide wheel is going to have less backspacing than a 8" wide wheel. As long as you're running at least a 15" diameter wheel that is intended for disc brakes, and you're running the typical 11.5"-12" diameter rotors, you shouldn't need any wheel spacers.

Well that depends on what you mean by 'Vintage'....what year range is vintage? To my knowledge, most aftermarket wheels are disc brake compatable, but it is possible that some '60's vintage aftermarket wheels are not. Take a look at the links that markeb01 posted and see if you can determine if the wheels will work. Like I said above, as long as they are at least 15" in diameter wheels with 11.5"-12" rotors, they should work.
