Craig, do a lot of research before buying from Kanter. They have a really bad reputation for junk parts among the Cadillac community and specifically among those who actually drive their vehicles.
Lifters, rockers, springs are crap. My engine builder will NOT use Kanter's engine stuff at any cost.
Steering and suspension components are weak. Leaf and coil springs sag in a year or two. Anything they sell made of rubber will disintegrate while you watch.
I have seen restoration projects still in the garage with brand new rubber bushings, etc that have never been on the road but have fallen apart while the project is on stands.
