Doing this now. Have a 254 in hand. If I try to mount it flat the adjusting knob thing (that changes the angle it will unreel at) fouls the side trim, on the RHS of the car. It should work fine on the LHS . Is there a 254 with the adjuster on the LHS? I like Demetris' set up, as it will avoid the belt rubbing on the seat squab top...but how would you do that extra hole on the LHS, with the tank filler hose in there?
