Rear lower panel

So after cleaning the under side and replacing the fuel tank and rear axle I regrettably started to check how bad the rust was on the back end 🙈 had to be done though!

I think its best I replace the rear lower panel rather that patch loads of bits. The spare wheel well also requires attention but not the whole tray.

Has anyone replaced the lower panel on a cab with the panel Heritage sell? Says it requires some modification to fit a cab, any pointers with that please.

I am literally in the same boat, just been given a Mk1 Cabrio and it has rust on the rear panel corners.

I have this exact panel, but have yet to fit it. I'll only need some small sections from each corner, but overall it seems a good match.

Stevie would you mind showing me a picture of the inner side of the panel, is it completely flat?

Apologies for the delay, I've been away from home. Here are the requested pics. As you can see it's not completely flat:

Thanks mate 👍
