hey guys i have got a 1989 mustang lx 4cyl im trying to find some production numbers of other mustangs of that year the exact same as mine. I was only able to find numbers for gts or lx 5.0 nothing for the four clyinders. I have access to fords oasis program (i work at a ford dealer) but the program does not go that far back. Does anyone have a site or list of lx 4cyl production numbers they can link me?
