This is a decision I am in the middle of as well. Car is a 1965 Barracuda and has 10 inch drums, but I would rather have discs... and I want to go to 15 inch wheels.
Wheel choices for the SBP seem to be limited. I am not a big fan of the SS Cragar, but they are available as new parts. Ansen slots are available, but I can only find 15x7's right now.
SBP brakes can be had from one end of the price range (Scarebird) to the other. I really don't want to spend 1500+ on a brake conversion If I can avoid it. The OE spindle assemblies are not common, and the ones I have found so far were just cores. By the time you replace the siezed calipers, worn out rotors, bearings & seals it gets expensive.
LBP wheels are much easier to find, since so many vehicles have used the 5 on 4.5 pattern.
That of course means doing something with the rear end. With a mild V8, the 7 inch unit will be just fine for me. So it is either new axles, or wheel adaptors in the back. I had not heard of welding up an axle for re-drilling until this thread - anybody have some feedback on that one?
Finally there is the front end & LBP discs. The expensive new stuff is of course out there. I see mention on here of a taller spindle from later cars, and various "digs" about bumpsteer. I searched "disc brake conversion" and read more than 400 posts. I still do not have a clear picture of what vehicles are good donors for that swap - "cordoba" came up a few times, but I have not seen one of those for a decade. The local yards around here have almost no RWD Dodge/Chrysler/Plymouth stuff.
I am watching threads like this one for more information.
Thanks everyone here on FABO. If I seem a little frustrated, well I am . The wife drove the car last week, and told me it would be a fun car if I could fix the brakes. She has no experience with manual drum brakes, and the increasing pedal effort scared the heck out of her.
