Help with Air Throttle

[Donald Spithaler]

Bill
I'm glad you have it fixed. Nothing like having trouble in your own
drive way. I don't even mind that.I have one of those valves for my
Horton fan on the curb side engine compartment on the frame rail & I
have seen the one in my drivers side engine compartment for the Bendix
cruise control. Where were you able to find one?
