Rarest sport seat ever?

I think there is waaay too much padding making the seat much more narrow. I'll bet if you re pad it to original speedster spec you will fit.

Yes, the booster are really stuffed, must have belonged to an anorectic rally driver...?

I will try to do a little surgery, do you think the vinyl on booster are original? Maybe they have opened them and stuffed them?

The tilting mecanism also look a little home made as the bottom part are some wider than the welded upper part.
It is a cool seat and I will try to ask earlier owners in Sweden for some history...?

The vinyl looks good on the bolsters, I think the carpet is wrong. Should be square weave maybe. Yes a very nice seat.
