Is it fine to just leave out the forward/reverse servo? If so, can you leave the shift lever as is, or do you have to pin it so that it doesn't slip into reverse?

Pin it, and/or remove the reverse gear. You can remove the servo. Don't want it flipping into reverse at top speed when you it a bump lol.

thanks, that's what I figured. Which way is reverse? Towards the engine or away? I haven't actually run this thing so I'm not real sure about everything yet.

reverse is towards the front of the truck. You can just spin the spurs by hand to check which way the wheels turn

Good call. I didn't even think to do that. I appreciate the help.

Anytime

Theres the spacer for the nemesis you can install. I think the part # is gs222. I think!!! You can go on the cen site and download the nemesis manual and i think it's on the 7th page with all the part numbers and it'll show you where it goes. Its real easy to get the tranny out and back in. It can be don within an hour!!
