Just wanted to confirm... a Serpent 811T-E body will fit.
I got one in to paint today and hacked it up enough to get it on the ET48 and sure enough it will fit. There is about 1/2in overhand on both sides, but thats nothing a little velcro won't fix up. I'd like to get some pics of it mounted up, but its for a customer so I'm sure he wouldn't be happy with extra holes lol.
