I have a set of bushings from Diamond Racing. The are p/n: 02-5028. They were bought from a member here a few years back and I never used them. The dimensions are 1.029ID x 1.096OD x 1.075. These are to use 460 pistons with a mopar 6.760" rod. Works to use shelf 460 pistons in a 429. According to the invoice I paid almost $50 + shipping. Make me an offer. I figure I would rather post em on here than throw it on ebay.
