heres a shot of the spot without the tube, its basically mounted to the 2 tabs that come down between the frame rails.
the tube I bought frome home depot for $5 its maybe 6" long and 2" diameter..heres all the pieces...
I guess a mailbox would work, no comment on the look..haha Some guys have mounted mock oil tanks under the seat that are made to hold battery trays. You can find them on ebay...You just gotta watchout for the chain rubbing on the bottom.
The filter part numbers are in the tech vault somewhere. Theres 2 numbers (one for left and right)
