My bad, Ed is right. Before you invest any more money make sure that you have the Manufactures Certificate of Origin. The original owner should have received one when they purchased the kit. Also, I would suggest contacting the DMV and get the regulations for custom built cars. NY is rather specific about what the car needs to have and you want to make sure that you are on top of it before you bring the car in for inspection. It is easier to install the components during the build process, than to have to retrofit them afterwards.
I am near Rochester if you want to get together and talk.
