Isn't the phrase "a decent rat rod" a bit of an oxy moron??
Be very careful what you buy & check that the car is legitimely registered not a "cloned" car as most of them are. The powers that be (government) are retro checking stuff like this now & vehicles of undeterminate or questionable heritage can be confiscated. There's a lot of uneasyness amongst an awful lot of rodders these days with legislation tightening up/changing all the time.
Might be worth checking out this site as it has an abundance of info re the law & registration
