From what I heard GV only wants to deal with people that buy from them. So if you buy used and need parts you are screwed. Think you need to dimple the floor board to make it fit.
yes, gear vendors are assholes. My brother bought a nice used unit off craigslist for 800 bucks. he needs the tailshaft for his turbo400 trans, since the unit came out of a motorhome. bastards want 2000 bucks for it...the same exact price for rebuilt unit plus he would need to trade his in.....which is damn near the cost of a new one. i'll never use any of their products.
