I would imagine since it is a roller your bringing in, the requirements would be the same as teh new kits that have been bought in.
Ie torsional beaming tests, seat belt anchorage tests, seat mounting, meet all current ADR's, emission compliant engine required, in SA probably no side pipes? Would also need to convert to R/H drive.

All the same stuff that any new builder needs to meet.

Check some threads and builds by guys who have done it, Albany Dave with his Daytona, Jethrow has just bought in a FFR Cobra. But these guys are in WA, so there will be slightly different engineer requirements.
