Thank you (sorry I'm a little late). Thats 7 3/4" is very helpful as the part listed in the TM comes back as only being 3 1/2". I would have wasted $$ getting 3" when I needed 7 3/4".
I'm still looking for that valve on the front and a lid for mine. I've found the Tee's and elbows. I have the 4 fill valves ,well atleast what the NSN gets you. They do not look like the ones that come from the factory. Nor are they what the PS mag says you need for drinking water. The one of yours with what look hose bibs is what it says you should have. I also have the quick disconnect for the MKT on the way. Now to make some new fenders and boxes, sand blast the frame, go thought whats left of the brakes,replace whats missing.
Gee, if I get all that done I will have a like new water buffalo.
