I'm trying to figure out if the seats I bought are 70 -72. There is a build sheet (found in driver's bucket). How can I determine the year of the seats? Model=13857, color=45 (metalic green)Vehicle Ident Number=13857OB SEQ No=872547 58 0471.

70 Monte Carlo

They were in a 1970 Monte Carlo from BALTIMORE Assembly, that was model 13857 in 1970.

Montel Carlo is a Chevelle series model and used the same seats and many other parts as the Chevelle

Great! Thanks for the info.
