I've seen them welded up in the past.I remember the old A guys telling me that they were probably Chevy centers with the Ford ends welded on.Now I realize they were just welded up.I actually got wised up to what they were when I was about 14.A local A guy took me with him down to the cape to pick up some parts,the fellow there explained it to me.Also,when I was about 14 I gave away a near perfect set of eyebrow fenders because the A guys showed me that the A didn't have any bead around the front.The old fellow that got them from me felt he might be able to find somebody that could use them on a hot rod or something.20 years later I found out from his boys that he knew exactly what they were,and that he had bragged about how he had swindled me out of them. There were a lot of A guys like that here,I bet there aren't three of them left now.
