Newbie, Keystone lift panel problems?

[Rayo]

Hi all
Just aquired a late 80's model Keystone in very good condition, with the exception of the front lift panels. previous owner replaced them with a home made set that were poorly done! Bottom hinge is unatatched so top can be lowered correctly.
Local RV shops out here in COLO want 425 to 850 to replace with new ones. I know I can make my own for a fraction. However I need a pattern of the originals. Anyone have paterns for these? Are the rear panels the same on this model? Any help would be appreciated!

I think the folks that made their own used the originals as patterns from what I have read. Might need to find someone who has the same era rig to take some measurements or try chatting with FWC or ATC guys.
