Roy, I don't believe your chassis is a scratchbuilt one, It appears to be a Pactra with some owned-applied solver in spots. Do a Google or Bing search on Pactra slot car chassis for a variety of photos. the Classic 26D motor was the best $3 bargain in the late '60s & they ran well stock. my guess on the Chaparral body is that it could be a Russkit, but I'm not 100% sure of that. You have a nice car there.
Yes, he said the body didn't come with the car. He handed it to Jim and said Jim was puzzled due to being clear, but he signed it anyway. He later had a friend paint it. He had it mounted with double stick Velcro tires to body.
Thank you Jim for the info.
