What kit are you using for big bolt pattern wheels

Scarebird makes a kit that will convert the front to BBP disc but retain the original spindles.
1965-72 Dodge, Plymouth "A" body, with 10" drums to 4-1/2 bolt pattern disc Wheel Kit

When I bought my SBP car it had adapters but the front wheels stuck out too far and beat up the fenders and looked goofy. I ended up converting to 73+ discs using junk yard parts. This is the cheaper option, but you'll have to source the calipers, caliper brackets, spindles, bearings, rotors, upper control arms, proportioning valve, and new master cylinder. If i had to do it again i would've just bought the scarebird kit.
