30-31 Roof Rib Wood

[Arty]

I purchased a partially complete car that came with 4 wood rood ribs. It has one roof rib (38” x 1 ¼”) (picture #1 and #3) is fairly flat and three others (42” x ¾”) (picture #2 and #4) that are narrower and too longfor the car have a slight bow. I assume the three longer ones are incorrect, but the 38" piece seem to fit good.


Most of the catalog show two different part numbers for roof ribs and I think three are the same and the forth is different.

Does any one know which rail I have before I go buy three others?
Can anyone tell me what the longer rails are to?


Thanks - Arty
