Vacuum actuators for A/C Heat system.

[Rangerman]

Got a leaking heater core and getting ready to replace it.

Also have the typical defrost/blend door problems. I got some good schematics for all the vacuum lines and I think I can figure it out.

While im in the heater box I might as well replace the vacuum actuators. I know theres one on the left side of the box, one in the passenger kick panel and one between the firewall /dash.

Is that the only 3 there are??
Anyone have the part numbers for these actuators??

Thanks
