1930's Door Check Information

I own a 1931 Reo Royale Victoria body by Murray . The car is in fair shape . I am rebuilding the wood suicide door pillars . The wood where the hinges sit is rotten . I am trying to figure out the door checks . I purchased 2 early Ford door checks 1931 to 1932 . This is a flat bar bent like a hockey stick with a rubber stopper on the end . Does anyone have any pointers on installation tips or preventative maintenance tips . I was thinking of trying to installing a rod like bearing so the edge of the flat bar can roll against this bearing . I was going to modify a house door hinge for the bearing . Also how wide are suicide doors supposed to open . Example 90 degrees or 45 degrees ? The door checks can only go so far. If you lengthen them they will hit the car sheet metal behind the hinge when they close . Any help would be appreciated . When you own an orphan car make , you have to improvise all the time . Thanks
