Craig, I did a bit of web snooping and couldn't find anything original or reproduction being offered now. I did find that The Filling Station also offers re-vulcanizing.

FWIW, the original part number for the 1960-62 235/261 single front engine mount is GM# 3763767.

I may have more info a little bit later when I can go sneak a peek at the 1962 235 I have stashed waiting to go into my 1951 3100. Will try to get back on that sometime later today. wink
