Mornin' Carl, I don't remember seeing Premiers name in my stuff but it's certainly possible.
Perhaps i should put in a call to a Cessna tech and ask if the tubes are interchangeable.
I gotta get out the door for work this mornin' as my help is waitin by the truck but i'll call you this weekend to discuss what we might be able to do.
I really appreciate your help Carl. Talk to ya soon.
