The only way to tell a mach in 69 is the window sticker or build sheet and the paint code. There are two paint codes for 69 mach. 1 for the body color and 1 ( I believe it is "5") for the blacked out hood.69 mach's also had 63C for the body code.I dont have my vin decoder handy at this time.It wasnt until 1970 that all true machs have "05" as the 3rd and 4th digits of the Vin.As for the 428 coming with shaker: Only the "R" code (5th digit of vin) had shakers.The "Q" codes had non ram air.Heres a site enter your data plate info in here.The data platewould be on the drivers side door if its there.
