We got our service manual for the 93 90 through Dyment, and it consists of 6" of thin sections, poorly bound, organized by service groupings. It was seriously expensive, considering we have used it about 4 times in 5 years, and then on only 2 cars. Don't remember the cost right now, but I believe it was on the bad side of 200 bux. I'm sure someone on the list can provide the phone #. HTH, John
