411 stbd lazarette cover details needed

Further to an earlier post, my boat (Corazon) is missing this cover -  a Switlik raft was placed there instead.  I am hoping to get a  new one made, the only impediment now is getting details about how the cover is made.  I would gladly compensate/trade/barter a return favor of some kind for these detail photos and measurements, realizing it takes some time, effort, and energy to do what I am asking.  I intend to take the details provided, then make detail design drawings from that data, then finally get a new cover made and restore the cockpit to original.

Thanks,

Geoff
