Sport Evo style seats and fixing them

[montecarlo77]

Hi folks
I am hoping to fit some Recaro SRD seats to my E30. They are bottom mounted, rather that side mount of the Recaro track seats) and will need some kind of adaptor, especially to adjust for the width of the chassis mounting points. Does anyone know if such a mounting kit exists?
I recall the original Sport Evo seats were very similar and had bespoke seat mounts with a little lever for angle of the seat base. I'm guessing these are NLA given the short production run.
Grateful for pointers, including any specialists who are known to to be able to fix such such problems.
Cheers

Proper bracket (still available from Recaro AFAIK) part number 67.70.09/9
