Mine are fixed.

Mine has the same seat mounts but they were pained black.  Maybe these are Microcell?

Mini seat frame

the recaro and bucket seat looks nice in the picture but i saw one in person inside the mini and it looks stupid and awful... the paddy hopkirk seats for me is the best , appearance wise, comfortability and it very light weight.

Well I picked up some seats that look like they have the mounting for use in a Mini, but not sure what they are.  They have snaps that come undone to remove the bottom seat cushions.  They look like they will be a pretty decent fit in the car.  Black with dark grey inserts and grey piping. The bottoms need the webbing redone.  Would post pic's but can't fiqure out how that works.

hardest part to find is the microcell with a mini subframe vs. homemade conversion

Microcell  is hard to find much info on seams like they made the Contour in a couple different styles.

Restall or microcell

I have a pair of original restall for my 1071

Microcell seats, the same as in Sunbeam Tiger and series 3 ,4, 5 Alpine, I am currently puting a set in my 63 mini.

These are Newton Commercial buckets in my car.

Recaro seats for the Mini https://www.google.com/?gws_rd=ssl#q=recaro+classic+mini+seats

Cobra seats  - SFX, SF3C, and SF5 (reclining)

Should get the list started.

How many different types of aftermarket seats were common for a vintage mini?

Pic's if available

Thanks,
