Clean backplate from a '64 Strat. The holes are slightly enlarged from taking it off and putting it back on but there are no cracks and you don't notice if it's on the guitar.
Personal checks are fine. Out of state checks clear in a day or two now. Wire transfers work. Sorry, no credit cards.
UPS mainly. In 45 years I've had one claim and they paid it. I don't like Fed Ex but I'll use them if you want. Don't expect them to pay a claim on a vintage guitar. Proper packing prevents problems. You got to double box expensive guitars and amps.
I don't buy anything I wouldn't want for myself. It's very rare I'll buy something that's not 100% original, but if it has changed tuner buttons or been refretted, I'll tell you. Detailed, accurate descriptions only. I go to a lot of trouble to pack this stuff right for shipping so it will arrive undamaged. 24 hour approval on guitars. I sell only really nice amps, fully serviced, no return on amps.
