i've got some frame mounts off of a 79 K10 that i parted out, and used some of the parts for my truck. 1 good rear spring front hanger (these like to fill with leaves and trash and rot out, which is what happened to the other one)i also have 2 rear cab mounts, 2 good front cab mounts, and 1 core support/leaf spring mount. the other core support is rusted around the hole, but the spring mount is still good. i'd like $10 each for them, plus shipping. i'm also entertaining offers. anybody needs any crossmembers for a 73-80, let me know by tomorrow night, they're going to the scrapyard if nobody is interested.
