Bell Housing Mount Help

[CRGRS 66]

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.

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.

i just got the 79-161 poly ones.they fit great,made by prothane,the metal parts are zink coated as well,i also went with the prothane front engine mounts,good quality.seems to me the only rubber mounts from anyone is offshore junk.i went with poly cab mounts also.cheers
