[Spridgets] Square Body Bonnet Stay

[fastvee]

I think that is the official term, although I call them prop rods. One catalog shows a rod mounted on the left side, the other catalog shows one on the right side of the bonnet. The rods themselves are different, and I was curious about when each was used. The RH rod seems to better support the bonnet because it is attached close to the center, and  I am looking for a RH mounted prop rod if anyone has one for sale, or trade for a LH rod.
