Looks to be some parts interchange with the F & G but the E is entirely different.
A good place to get them is Kenco Mfg in Atoka, OK. That's where I got mine when I had it. I had to turn my hoses around on the quick drop valves (on top of the lift cylinders) I remember. I think they were around $800 about 5 years ago. They look exactly like the ones on a late model D7G.
