Dwight,
Couple more pics for you, I don't remember the Cobra Seats (but then I Don't remember that much of the 70's - bit of a blur). I made the seat pan out of 1.5mm Gal. sheet,hand rolled the shape and then folded down a 10mm edge all the way round to give it rigidity, affixed the mounting points & rubber buffers, the took it over to my mates place (motor trimmers) along with a Carton of beer & a bottle of bushmills and carved & trimmed it on a friday night - if its a bit rough then I blame it on the beer
