I have some SS springs for the BB, to be exact like 200 or so sitting in the cabinet.
I got 2 of those already (and a couple of BB hot springs in the drawer too).
I don't have a SS spring for my SB though... and that might come in handy in the future (but I don't think you have any of those either). Heh, next old SB that comes in for service or something you could "...as a bonus gift in appreciation of your patronage I've taken the liberty of replacing your old stainless steel spring with a brand new HOTspring free of charge." can't beat that (I'll pay for their hotspring and promise not to tell).
