Welcome to the group, I'm looking forward to more photos too! The damage looks pretty minimal and replacement panels are out there both new and used, some appear on eBay so worth checking regularly. I'd recommend getting in touch with Mark Wastnidge at BetaBoyz, he's in Axminster and usually has a Summer garage day, it's a long way but you'd be surprised what he has in stock. Last time I was there I think he had a brand new set of early red velour seat covers? Gotta be worth a call!
