Have you had good success with these on 1500 carbureted cars? I used a new replacement 1300 style mount on my 79 which failed (axle rubbing on crossmember) within a few thousand miles. MWB states this is because the rubber is softer than those used on 1500 models, and the added weight/ softer rubber causes them to sag.
If you've had good luck with this one on a 1500 for $58 im in!
It sure would be good to know where some of these "stories" come from.
Fiat did not differentiate between 1300 & 1500 mounts, only if they had the extra hanger for the exhaust system.
I suspect what you are referencing is instead different hardnesses of rubber used by various aftermarket mount manufacturers?
If you are rubbing your 5 speed inner cv joint on the crossmember you need to look at the entire mounting system as something else is failed.
If your car came to me for service I would have no issue using the mount, and to date no one has complained about the quality of the mounts I am buying in Italy made specifically for this application.
But please keep in mind that the mount has lots of stresses and lives in a harsh environment, so if there are other issues the mount, being one of the weaker parts in the system, it Is subject to failure.
You have already identified a bent lower cross member, look at the entire system and fix it, not just the part that fails because something else is causing it!
