So here is some backstory SGNT64, @WV64Signet is a buddy of ours. He has been wrestling with his 904 for quite some time and only recently got it sorted out. Whenever I wanted to poke him I would just tell him to drop a four speed in it! He ignored my advice repeatedly (as he should) but myself and several of his other buddies continued to heckle him about the four speed! Hence the reference above. You will find this group has a wealth of knowledge and will never hesitate to help you in any way we can. Of course you do have to put up with a bit of heckling!
