I don't recall ever seeing a posted attempt to get one going. Just takes someone to contact the vendor and see what's possible, if anything.
Gear Vendors 800 number is 999 9555, Mike is probably the guy to talk to. He is easy to talk to, as in not a jerk. I'm not sure how flexible GV would be with their prices. Bob H.
I've been torn between the GV and a 200R, I've read that you do have to do a bit of weld work on your rear trans cross member to make the tailshaft sit at the correct height.
I use the 2004r with a lockup and 373 gears. Does real good have used it with nitrous and have gone 11.80 with it. It has been in the car for 10 years now.
