WTB: V8 K Frame - spool type

Did you get a spool mount k frame and is that what is out of alignment - the placement of the mounts? Is it definitely an a body k frame? If so, I'd cut the mounts off the K parallel to the ground, leaving part of the old bracket attached so you have something to weld back onto. Hang the K back in the car, and reinstall the motor in the car with the motor mounts attached to the block and the cut off ears attached to the mounts. See where they land, mark, disassemble and weld.
Maybe we can straighten out the one you got with a little cutting and welding.
