Talked to the guy tonite, its purportedly number 183 not 160, ex calif import, sounds like lots of changes have been made, no ali cockpit surrounds, not orig motor,identified build number by ali tag?!(explained you have a number stamped on it, subtract 24 and thats your body number?) on bulkhead adjacent to volt regulator?, not orig g/box, yet has cert!
suggested he look for number stamped on trunk lid bracket
just looked at my cert, had 5.50x16 tyres fitted, a typo?
