Truck is an IDI and has a vacuum servo.

I think I've narrowed my cruise control issues down to the servo.

Problem is, a new servo seems impossible to locate. F0TF-9C735-AA is the part number. I've found quite a few that match in numbers other than the F0TF at the beginning. Have no clue what difference it would make.

Was there an update to use a different servo?

This is the only non functional part on my truck and although I may not use it much broken stuff irritates me lol.

Any help is appreciated.
