Early 65 Slant 6 to 340 engine mounts

Easy enough to do yourself with the 273 brackets if you're so inclined.

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.
