In terms of the seats, the fabric may clean up, and new foam, diaphragms etc (etc) in the seats should take out the sagginess/creases in the fabric to some extent. If the fabric has come away from the vinyl sides, they can be rejoined (I have done this in my 1989)
If you need new fabric, try Newton Commercial though they tend not to have the rarer designs. The same fabric was used in 1970s MGBs (usually in grey but sometimes in orange) so nosing around an MGB forum might help as MG owners tend to take out the stripy deckchair seats and reupholster in leather so someone may be selling/binning a set which you could adapt.
Hi some1158,
Thanks for your advice, I will keep an eye on the MG sites, to see if something come up that I can use. Are the MG seats the same dimensions as the Mini? Front anrd rear? Thanks.
Cheers
I don't know the exact dimensions but the front seats are definitely different as they have a headrest. I imagine it would either be a case of trying to fit the MGB seats in your Mini (possibly a shame if you're after originality, always assuming they fit anyway) or taking the fabric and getting it made into new covers for your existing Mini seats.
MGB rear seats are different too - there is just a bench (in the GT)
(for comparison, here are the MGB front seats: https://www.ebay.co....s-/174240713626)
I would definitely start by looking at your foam and diagphragms: replacing them on my 1989 has made a huge difference and what were saggy covers now look much better.
