panel or sub barn door supports

[psycotruckr]

Does any body out there have any ideas on how to make the door props on the rear doors functional again. mine are in reason able shape but I can not get the stops to work right. I have tried to clean them up and they seem to slide well and the catch moves freely but it will not engage like it is supposed to. How about modern gas prop rods has anyone tried these? I know this is a PU site but it also has a knowage base unmatched on the internet as I can find so I thought I would start here.
