Stripping out of the interior continues, but it was too hot to work in the garage today, so spent some time cleaning up the passenger seat to see how it would come up. Still needs another clean or two, and the foam and backing boards on the seat bases and possibly the back need replacing, but I think the cover is savable.
The problem I have is that the driver's seat has some damage to the bolster, and the seat back cushion. And although Martrim in the UK seem to sell the basketweave vinyl, it doesn't have the "ribs" which seem to be melted in, which gives me a dilemma. Do I try and replicate the ribs using heat application, or does anyone know if the right material is available elsewhere? Or do I recover both seats, which would be a shame - I'm assuming that the vinyl is original? I really want to get the seats "right" if I can, they're as 70's as an orange Spangle!
