79 xs750 triple questions.

What's made in way of seats for my 1979 xs750 special? Or am I going to just have to make one my self? I've never done fiberglass work so I'm really looking at buying one that has the spot for the round taillight. Any options or is custom the only way?

Oh and I'm going to have a rear hoop welded in as well after I pick up my seat if that changes anything

You can always make the pan from thin sheet steel instead, at least i think its easier and cleaner than mucking around with plastic.
Never heard of xs750 café seats myself.
