Has anyone used non-Nissan strut mounts, suchas the KYB SM5064? Its killing me to spend $70+ on each mount!

KYB SM5064 Strut Mounts

Careful. I think someone else was wondering about that KYB part in an earlier thread. I think KYB SM5064 is only the front strut bearing, not insulators. Google that part number, you'll see other examples.

The only true "replacement" strut insulators are the polyurethane one's MSA sells that have some level of caster camber adjustment, these I believe

Motorsport! Street Camber Kit, Front, 70-78 240Z-260Z-280Z - The Z Store! Nissan-Datsun 240Z-260Z-280Z-280ZX-300ZX(Z31/Z32)-350Z-370Z Parts... $129 a pair.

$73.95 for an all new Nissan strut mounts is a very, very reasonable price for a part that will last 30 years.

exactly before bashing the part, realize the first one lasted 42 years.... (as on my car)

That is just incredible.
