Bell Housing Mount Help

My bellhousing motor mounts on my 66C10, with original 283 are quite swollen, and cracked, are these the correct replacements, and should I stick with rubber, or go with Urethane?

Also, have not pulled the engine yet, and the front mounts look good, should I consider replacing these as well? If so, do I need to replace the entire mount, or is there a "rubber" that can be replaced?

Thank you in advance for your input.

Those look like the correct ones for a manual transmission.

Re: Bell Housing Mount Help

Urethane has a higher load bearing capacity, greater tear strength, better compression set, greater abrasion resistance, is more tolerant to greases and oils. I feel its worth the extra money personally. Rubber is biodegradable and is affected by ozone...they will dry rot and degrade over time. Urethane will keep going and going.

X-2 if your keeping it, although they will transmit a little more noise...but you are insulating the cab so it shouldn`t be an issue.
