Motor mount for 64 valiant

I got some for my 64 Valiant 225 recently. You can find individually or a set on ebay for ~$20/set. Do some checking since some listings are wrong and the photos are often generic. Autozone can get but $25 for the driver's side one and the same rubber type. My problem is they don't appear the correct thickness. The passenger side one is a bit too thin so the engine slants over too much. The prior owner put a worn disk brake pad as a washer to lift it up. Putting in a new mount didn't help. Maybe the driver's side ones are too thick, but the oil pan is already just above the K-frame. Search FABO, slantsixdan (god of slants) says the made in India rubber ones fail quick and better to spend ~$100 for a set of polyurethane ones. I'm a cheap bastard and will know in a year or so.
