just up plug it. I had a gear driven one before I got my new trans and I ran in the same problem as you. Make your self a blocking plate and cover the hole on the trans and be done with it. Thats how mine is ya the speedo doesnt work but that what the tack is for just drive around and pace...
I'm going to take his word on it, but thats just me. Slide on over to corral.net and search threads containing nickmckinney and see what he's been talking about cams over there. He's very informative.
