I talked to Barry on Monday, Barry told me that the vehicles being produced for the 1971 year at Hamtramck was the Dodge Demons ,Dusters,Valiants and the E bodies I have not talked to him since, but what Iam trying to figure out how the (sequence Number on the buildsheet ) and the (Sequential number last six digits on the Vin ) work and when Hamtramck was building these cars were you getting a Demon coming down the line then 2 or three dusters then 5 Valiants and maybe acouple of cudas because my sequence number is so early it is 1|0005_ _ and My Vin is LM29H1B102_ _ _ built on Saturday August 8 1970 I might just have get a hold of Galen
