Man, I've been thinking it might be pretty cool to just take the BSA back to how it was originally. A rough restoration I guess. I wish I had the original seat, I was looking at the photo and it looks like he took a king & queen, then cut the queen segment off so it was like a cushy drag seat? And he didn't sew it up either, just folded it under and bolted it on. Rad.
My plans change more than my underwear but for now I think this is what I might do.
