Steve, Darryl has a great pully and it works well when you can find the pump. I don't know what auto supply store you go to, but nobody in Dallas, Texas stocks the pumps for Darryls pully. They don't even stock my pump for the push on pully.I have to order them several at a time to get the price down. We have to remember that we are working with a 20+ year old car and stores arn't stocking for V6 Volvo engines. Most are going to the crusher. Fact is that most people have a hard time Identifying which pump it is. I sent one to England because they were even having a hard time identifying it. They finally did, but they couldn't for a while. John << Same thing with the water pump...I purchased the common available Volvo water pump with the bolt on pulley and purchased the bolt on pulley for it to work with the Delorean from Darryl. Again, no special presses needed or having to wait for a shipment to come in...trip to the auto parts store and I'm off and running again. >>
