The 37 trucks had a split seat bottom. 2 years ago I traded my 37 seat bottom for a 1 piece 38 seat bottom at a wrecking yard in Nevada. Sometime before I bought my truck, it was converted to a 38 style gas tank with fuel filler sticking outside the cab on the passenger side. My seat bottom was in great shape with no broken springs, wire brushed and painted with Hammerite. The wrecking yard is D & L Auto Dismantler in Moundhouse, Nevada, 775-246-3444, ask for Roger or Richard Haas. They may still have it. I know the exact location in the storage shed where I placed it. Roger & Richard are brothers who own the yard and very helpful. Don't know about shipping to Finland.
