I've thought of it... I don't think it'd be too tough if you've already got a clutch that utilizes a 1-3/8 IP shaft. Maybe a custom Driveshaft, and you'd be rollin.

One other thing I do not know about on a second gen would be where the shifter come out and how the hydros would work. Because I dont know about the throw of the clutch fork as well

I think the hydros are the same. Basically its the master cylinder mounting that's different between them. In fact, I have G56 hydros on my NV4500..... Sent to me by accident by Valair. Had to trim the arm a little, that's it.

Yeah I kinda figured the slave was the same. I know you cant do second gen hydraulics on a third gen. They sent my buddy vinny 2nd gen ones for his 3rd gen and we couldnt get the truck in gear
