Have seen several references to replacing the vacuum motor (or 'solenoid') on the front axles of the G2 trucks for ~$35. 00. Every quote from every dealer here in MA is $130. 00. Does anybody have input on this? Anyone have a P/N in case I'm getting a misquote? Many thanks guys! I have been very specific at the shopsÑNOT looking for the whole axle casting, JUST the vacuum bladder which C-clips into place in the casting and carries the shift yoke between 2 additional clips.
