LOL, yea, probably would've been a better idea but you know how it is....why buy it when you've got it?.....lesson learned.


are the poly mounts less prone to splitting and separation? seems like it hasn't taken much to rip the rubber ones. i've never even put slicks or drag radials on the car and tried to get it it to hook. still ripping rubber mounts with just some street driving and possibly the occasional full throttle 3 gear slide away from a light...

Yes all polyurethane mounts are interlocking so they can not separate. Factory had interlocking motor mounts as well but they were only factory installed on engines rated above 300 horsepower. Everything else still got the glued together (Vulcanized) motor mounts that prompted the very first ever factory safety recall in 1970.

Re: Solid motor Mount Question

Solid mounts for the right engine size are a direct replacement for rubber/poly, so you’ll be fine.
Solid are not as harsh as people think, but you will notice it.

That said, unless you are making crazy power and hooking hard or just generally beating the hell out of the car a good poly or even rubber replacement should not break.
I have poly engine mounts and a rubber trans mount, mines an automatic so not quite as violent as a gear car, but they have lived for years behind a 500 horse 406 with a lot of 1/4 mile passes, and now a 600+ ish motor (but no passes yet). You don’t need solids unless racing or lots of power and hook.

The old cable or chain or whatever was a bandaid for the non captive type motor mount, so there is no reason for that mess (in my opinion) to be hanging off the side of your motor. I don’t think you can buy a non captive mount anymore.

But hey, if you want them solids will be fine, just not necessary in my opinion.
