Hi Ronnie,
I think this is what you are referring to.....

This should work, the problem is that since the door and the retract are on different planes, when nose wheel is retracted the cord may rip off the brass tubing and if it is adjusted just right then the the door may not get pushed out in the open position properly.
It may have to be a swivel arm which would scissor (collapse) when the gear is extended out and then straighten when the gear is pulled in. I am pretty sure i will still need the mounts that you mentioned above. Thank you....
