Hi,
I have done it to mine. It was a 2 door survey hard top but I bought the 5 door body off ebay (V8 incomplete vehicle) and swapped them over. A chap in Sydney was more than happy to but the 2 door hard top body. Series bodies won't fit properly without fiddling but a 110 body of any sort mounts up fairly easily. Troubles plumbing the fuel tank up if going for the 4 door body and you will have to source the intermediate body mounts as the 2 door soft top is esentially a van without a roof and the sill panel doesn't go further back than the front door and uses different mounting points on the chassis.
Any hard top 2 door bits will fit straight on but you may be limited to fitting the 4 door body for the hard top option as was said about availability.
Cheers,
Brian
