Trust me, I have friends that studied every number being correct. And they pay for the one letter in the VIN. I totally understand this side of it completely.
But, two things:
1st, I would destroy numbers matching by pulling off what I didn't like and installing what I did like. Like going from power to manual steering, brakes, etc. Then the factory A/C gets in my way and off with that. I don't know if you ever followed any of my threads, but if you did you'd see the car of topic in this thread would NOT appreciate my thoughts and ideas.... (speaking of $$ side of things). :D
2nd, for toy money I didn't have 6k to buy H-code stuff in the late 80's, and I don't have 20-30k to buy it now.
