I can help you only a little. It is my understanding that the Chevy roadster PU is VERY rare. IIRC, none were made in the states but don't quote me on that.
There is a member here who may be able to help you with the numbers but his name escapes me at the moment.
If you go to the VCCA forum there are people who can rattle those numbers off their heads.
Due to its rarity I would strongly urge you to keep the car original.
If not, sell it to me.
