Early 65 Slant 6 to 340 engine mounts

Thank you.
I don't have the 273 brackets. The car came with a slant 6.
I do have some 318 brackets form a d150 truck. If I cannot find the right mounts, I'll look to modify those. I don't have problem with fabricating and/or welding things. Just trying to make my life easier.
Just suggested as an option to the aftermarket mounts that aren't available anymore. Your early A K frame is the same, be it slant 6 or V8, so scoring a set of 273 engine brackets will get you there. And yes, truck mounts have been modded to work, too. Best of luck!
