Interesting as the pass side is what failed on mine - I also found out that there is no high RPM skip in my engine

I'm going to replace that side then the driver's side later - assuming I can get away with it for a while emk[]jmmsx w

Hope this makes sense - the poodle pup just helped me type

If the passenger side tore it was probably bad vulcanizing (or whatever that bonding process is). Generally, the one on the drivers side is what tears loose, from my experience. I had the same issue on my 68 Mustang with the 351 Cleveland in it, but I just chained the engine down on that side and no more breakage.

I agree 100%. I've never seen a passenger side fail except for the time I let my '60 348 hang from the front mounts and the exhaust pipes as I pulled the tranny for the first time (we learn from our mistakes, sometimes ) The torque of the engine lifts the driver's side and tends to compress the passenger side. Unless your frame mounts are spread a lot putting twist on the mounts I'd say you must have gotten a bad mount.

Go back to my original picture, not the one Don marked up and you can just about see the vulcanization failure that led to the rip out of the main body of the elastomer. The replacements will have some through bolts. The later Ford motor mounts, '75 up, were fully captured by some brackets but are not, unfortunately, interchangeable as they locate the engine differently.

A note on that - if that board is so exclusive that only members can see what's there, they will not grow. That is unless they don't want to expand

Dave that was just a link to a thread on a forum, not the company web site.
They have been around for a long time & have a huge, huge inventory. If they don't have something most likely Mike can rebuild the old part or make a new one from scratch.

OK - that one I can access. The other just dropped me at the log-in with no where else to go.

Lots of interesting stuff - I'll bookmark it just in case, but for about $15 each will just replace in kind what I have with some reinforcing bolts. Thanks for the link
