Looking forward to your results, George!
500k pots for volume and a 250k for tone work best for ThunderBuckers, I've been liking a .1 tone cap lately. You can wood block the pup cavities to where they're 1/4" deep maximum. Then use a 1-1/2" square by 1/4-3/8" thick piece of foam to replace the springs, a narrow piece of foam works better than a wide one for some reason. Getting the studs in the right place turned out to be easier than I thought it would be when I did Scott's JAEbird, give it a shot!
EDIT...I just checked the stud location on my '77 compared to my 64s, they're very close to the same place. I'd suggest remounting the bridge you removed so you can find find the intonation points. Then work from there to determine where the studs should be for the Badbird to properly intonate.
