Hi, can you weld/fabricate? Take great care to check out the chassis,outriggers and bulkhead, it can be easyier to do a clutch, engine rebuild etc. than having to try and weld up a rotton bulkhead/chassis. A friend has just had to have work done on a SIII engine and was staggered how cheep engine parts were, and how helpfull and low cost local small engineering firms were.
Good hunting and let us all know how you get on.
P.S. thought of a airportable??:-)
