Need main bungee assembly for manual gear F model

[M20F-1968]

I need to find the main bungee assemblies for a Johnson bar F model Mooney.  The applicable part numbers are:

 

Whole assembly - 560138-503

 

Which consists of:

forward cylinder/hat No. 560117-503  measuring 23" from the hat forward and 29.3" overall

Aft cylinder No. 560009-501

Bungee spring No. 916002-000

 

Please advise if you know where there is an F model that may have these parts or if anyone might have the parts.

 

You can e-mail me at johnabreda@yahoo.com  or call me at (617) 877-0025.

 

Thanks,

John Breda
