Hi All,
 
So I decided to buy bargain of an Avid MKIV.

It has a high hour 582 bluetop (255 hours).  Compressions and bearings are all good so I am not overly worried....especially as I paid less than $6k for it.  It is ultra different to flying Cherokees 6's which I am used to....but it is massively cheaper for simply burning holes in the sky just for the fun of it.
It used to be a tail dragger but some monster converted to a nose pusher.  A few things I want to do it:
 
1) Convert it back to tail dragger.  I have seen some undercarriage options from Airdale, but they don't respond to email or answer the phone.  Does anyone know if they are still in business? or anywhere else I can get taildragger kit from?
2) I want to replace the doors the Perspex or whatever it is called these days.  Again anyone know where I can buy a set from?
