Was it on ALL 70 M code automatics?
Don't know if export cars would have the system though believe there is a good chance they would.
Due to Federal standards my answer would be yes Ford expected all 70 M code automatics to have come as federally certified - with the system
Like other emissions systems allot of them got removed (either completely or in part) over the years. Remember allot of guys thinking that the speed sensor attached to the speedo cable had something to do with cruise control
Easy to check for mounting holes and signs of missing or present components of the system
