One more thing Richard, what struts will work with these retracts.
Go with Robart 7/16" diameter oleo struts. I don't know how big the main wheels are, but Tower only sells offset struts for 3-3/4" - 4" wheels:

For smaller wheels, you would need to go with 661's or 662's if you want 7/16" diameter struts, and those have to be ordered directly from Robart. Tower does carry 3/8" diameter offset struts for 3" - 3 1/4" wheels.
