Is your car a factory big block car?

Reason I ask is that factory big block cars have a HUGE cutout on the passenger side inner fender. My wagon is a factory big block car and I put solid mounts in it. Made a noticeable difference for the better over the factory rubber isolators. There just isn't much support from the inner fender on the pass side on these cars.

Think of it as putting subframe connectors in except that you're tying the (front) rails together side to side instead of front to back. How are subframe connectors usually mounted?

Ride harshness is no different than a '72 - back Mopar. My wagon was a daily driver for 5 years with the solid mounts.

Go solid. My
