No problem! I'm working at home today so it hasn't been a chore to put the kettle on for a cuppa and nip into the garage to take some pictures!
'Vinyl' always conjures up images of something slightly tacky but the Fulvia seats are very good quality and still look fresh after all this time.
I've taken five more pictures and named them with descriptions I hope are self explanatory. The front squab has a large seam at it's front before the vinyl is taken round and simply stapled underneath. I've also taken pictures of where the squab and back meet at the sides and the top of the back seat. There is no seam at the top of the back cushion which just seems to smootly run round and is, presumably, stapled much like the squab - the 'SeatBackFromRear' picture was taken through the rear window.
Hope this helps.
