Fair enough. I see your point
The panels are replacements. Just couldn't get a straight answer when searching as it was 50/50. Perhaps the early parts were overlays? Thankfully Chris at Tarmac confirmed for me.
As for fitting, this is still unknown but I do know the original panels are welded so they'll need removing and the carbon panels I guess, like you say, will be riveted in place.
As always I'm just going to roll the dice and go for it. I've been quoted about £1200 per side to buy, fit and spray new panels so this has to be the best option. How wrong can it go
