Wanted: DX components / ATAC stem / A'stars seat collar

[AK74]

I'm tracking down the last remaining parts for my Cro-Mega rebuild, and would like to find the following:

- Shimano DX freewheel hub (FH-M650) ACQUIRED
- Shimano DX seat post (29.4 x 300)
- Answer ATAC stem (1 1/4, silver)
- Alpinestars QR seat collar

My preference is for NOS, or used in excellent/very good condition.

Thanks in advance for any help (and 'yes' I'm keeping my eye on the For Sale and AuctionWatch pages).
