340 Motor mounts

Yep. And the RH spool fits all 273, 318 ,340, 360. I think they standardized A, B, C body mounts an an effort of austerity kinda like the brake pads, and wheel bearings because of costs. GM did that **** for years. It's a shame Chrysler learned that too late.

I'm not sure "Chrysler" ever did learn "that." AKA before I sold the 3/4T gas automatic truck, I was considering converting it to a 5 speed (it's a 360) One main reason I didn't is that it was standard cab. Anyhow the 360 WAS NOT DRILLED AT ALL for a pilot bushing.

And I've always thought putting balance weights on the converter instead of the flex plate was stupid
