I have been wondering for a while about some hood retainers I have. They are for 28/29 model A's. Attached is a picture of the two hood retainers I have. The top one has a pair of stiffening bridges on it and the lower one doesn't. I am wondering if one was used on 28's and one on 29's or if they are just made by different vendors taking a little liberty in making hood retainers for Ford. Does any know anything about the two styles? This is not a big deal, just curious.
