I thought that I should start a new thread on this issue in the interests of not prolonging my 'welcome' (or over doing it).

Seats: Supposing I can get some decent originals and have them re-trimmed in a period (circa '68) manner, will these seats be effective and supportive (for everyday driving, not racing)? OR should I be looking at repros, such as BF Torinos, Vintage, Historika, etc., for such an outcome?

I also see that Pelican have seat base and backrest covers - have any folk used these on their old frames and cushions?
