D8 2U information?

I'm looking at buying a 2U D8. The serial number is 2U20860? What can you tell me about this machine? How many hp? Wet clutch? Shuttle shift? It looks like it has a lever to the left of the gear shift but nothing looks the same as my 17A. The rails and grouser measure like new and it has a segmented sprocket on one side. Will this machine be much more than the 17a? What is it worth? Rebuilt engine and heads 15 years ago but was never used and is stuck currently.

Does anyone know if the rails and or track pads will fit my 17a? They both have 8" pitch it looks like. The 2U has new rails and grouser pads. I thought I could maybe take a couple links out and use the tracks if nothing else.

NO although they are the same pitch the bush size is different.
You will find the plates are the same but the bolt holes are different.
