Hi Ebbie,
As a fellow Archer owner I really feel for you, especially as I too have had some internal trims renewed.
You might like to bring this over to Facebook where there is a very active group centred on the Arrow but in reality serving all Cherokee variants. Most of the contributors are in the USA but you will get support from all over the world.
I have no vested interest in promoting the site but it's doing a very good job for those of use who have Pipers.
