Hello,
I'm a former owner of 6T09K134680. It was in my family from late 70's until I let my Dad {regrettably} sell it in late 2004/early 2005 when he had terminal cancer. I've just recently thought of trying to track down the car and saw it mentioned on this site. I have a lot of history on the car from those years and some background on the HiPo engine that my dad put together from original parts for it if anyone is interested.
I'd love to have the car back but I see it's been restored into a GT350 clone so it's really not the same car I remember. Regardless, if it was for sale, I'd be very tempted.
Matt
