oh and about getting info from my family... my great grandfather purchased the truck at they indy 500 in 1975 supposedly from a crew chief or chief mechanic from one of the teams. (he worked in promotions and was promoting the race that year) he drove it home to Washington. he passed away in 1978 and the truck was willed to one of my uncles who sold it to a family friend. he drove it for years until the fuel pump went out causing it to be parked. I purchased it for 200 dollars and drove it home. my great grandfather knew alot about it but no one in the family seemed to care so no one knows anything more than he brought it home from the race
