The car should be wired for a CD changer if there's a CD button on the stereo. You can pick up used factory CD changers on eBay for a reasonable price.

I have a 90 LS400--it has a cam seal leak. The motor has 225K and runs like a top--but should I replace the Cam seal or just purchase another motor from Ebay? Dont know which avenue to take

If the engine runs great, a cam seal is a lot less work, time, and money than a new engine. You could also take that opportunity to do an ahead of schedule timing belt change and change the other cam seal.

My 90 LS400 has 15" chrome 5 spoke wheels. One of them has a bit of wobble and I want to replace it. When I look for wheels using the year and model none of them look like mine. Can anyone identify if this came from another year or model, or if it is aftermarket?

I used the gasket that came with the filter kit when I did mine, and the gasket disintegrated completely in 2 days. Bolts were torqued to spec. At least I was practiced for the 2nd removal. The sealer alone worked fine. Removing the exhaust bracket makes the removal and installation much easier. It took a long breaker bar and a 6 pt socket to loosen the exhaust bolts.
