Be careful what you ask for.
I've been in touch with Roger at Chevron /Tiga and appreciate the help finding him.
Someone has suggested the engine cover and intake are from a Swift DB1.
Not much else appears to be original body work. If I've done it correctly I have attached a picture of the car. Tiga # 37 from 1977. I did not receive the log book when I purchased the car in early 06'. I believe it has been in the Houston area unused for 1-2 years prior to that and that it came from the Phoenix area? Does anyone recognize the car and can help me out with it's history? Thanks. Jim
