Hi mat,
you siad you are going to just oil the srpings,
If this isn't road worthy then ii think that would be the best choice as well as parabolics would be abit of an expense if it never goes on the road.
As for seats, that shal mate a superb differnece as we talked about. Get a cheap pare of the scrap yard,
heard all sorts go in, its just what you can get your hands on i believe,
i have peugeot 205, heard of volvo's, peugeots 306, meastro's, all sorts,
me xx
