Get some pictures up of the rot, inside and out, it'll give a better idea of what's involved, it certainly won't be the cost a campus plus the labour to swap everything over. If you're able to strip and retrim the car that will help keep the costs down. Regards fitting the kit to a campus shell, personally, it's better to bond it on in the normal fixing points, after all it's those points which is why they rot and why campus's don't.
Regards the vin, it's only rivited on and that's what mot'er will check, they can't check the stamped turret numbers if there's a strut brace covering them, not that I would suggest you do such a thing
Regards the shell difference, there's actually quite a few.
The rear arches, but they're only single skin so can be cut back to look the same, remember to paint the edge to protect from further rust.
There's also no mounting lugs on the sills for the side skirts, and if you get a campus with the door/qtr plastics they will have lugs that need to be removed.
There's an extra panel welded on the os inner wing which the anti perc fan outlet slides into.
The battery is on the other side, the campus doesn't have the battery tray, nor the holes for the tray to bolt into.
The front bulkhead panel has different holes, where the Gtt aei module bolts to, the perc fan solinoid brackets rivit on and where extra loom such as brake earth wires pass through.
The back bulkhead has an extra hole for the choke cable to go through.
The os turret has extra holes for the brake fluid reservoir bracket.
Also, you can swap all the other glass as they have seals but the front screen is bonded in, campus's have clear glass and Gtt's are green tinted, depends how genuine you want to make it.
Personally, save the Gtt. I'm near Liverpool if your stuck for someone to do the work, whichever way you want to go with it.
