On my 38 we had to cut part of the back of the metal around the tank. the metal to support seat wrapped around tank and we couldn't move tank enough to get it out of frame work. Looked like tank had been put in place then the seat base frame spot welded in. The straps didn't have springs and cotter pins. The cab mounting bolts did have springs on underside forward, on the rear cab mounting bolts the springs were inside cab. Your 46 may have a better system.
