Hi Hhariri,
Welcome to the forum, where abouts in the UK I'd the vehicle? Perhaps someone could go and have a look at her for you.
The engine is long in the tooth, I'm not sure 65 would be considered it's cruising speed...
The key things are the chassis and bulkhead, if they are good you're golden.
Once you get it to the states are you able to modify it?
Cheers,
Mike
