Problem is I managed to lose the 2

It doesn't seem possible to buy a replacement anywhere so I guess I'm
going to have to buy a different seat anyway. Very frustrating.

I've got a salvaged one here in my box of "bits that might come in useful
some day but seldom do" (TM). It's a bit rust stained but you're welcome to
it if it helps, my reply address (but not the from address) should work if
you want to email me your snail mail address.
