I just bought this The late 60s look, simple head light mount. significanlty different looks than my 1971 T350.

I see a lot of these early T350/T250 seat foams looking like they dried up, sag, lost volume. Is there a replacement foam or way to boost the volume, or another bike's foam to leverage for OEM like fit?

What have people done to fix the seat cushion on these type bikes.

Thanks
