'unlike a '36, a '38 has the gas tank under the seat like my '37 except they moved the filler outside and put in a full bottom seat instead of the split flip up for the gas bung. yes the 3 notch thing is how the seat back adjusts. the bottom is stationary. they were all metal springs, no wood though the adjusters and mounting rails over the tank frame came out a few years down the road. Mine came with the wrong springs so I'm not sure the exact way the bottom clipped in but if you are fabbing you can be more creative than the original lame engineering and still look original.
