Thanks for all of the replies fellas. He has spoken to Dave at Pro Trans and he likes what the man has to say. They discussed what he does with the car and some of the components that can be used in a 904 application. He was familiar with the company that he bought his converter from Continental who are also in So Cal. Dave basically got all of the information that he needed from my buddy and told him he would get back to him with a setup and cost that will cover all of his needs. My friend said he was very confident that Pro Trans knows what they are doing and will supply him with his next transmission. Many of the other guys mentioned are competent as well, but dealing with a guy who is in the same state has its benefits and saves a bit on shipping. Plus doing some reading on guys who use this shop for there trans needs shows they know there stuff!
