Seems I have a few options:
-Buck the elongated holes, and perhaps drill a new 3rd row for good measure to stop movement shearing the rivets.
-Shift the shell to one side 1/3" or so and make completely new holes on the plate.
-Re-drill everything about an 1/8(?) bigger and use a larger rivet
The original rivets had 1/8" diameter shaft, & replacement rivets from Vintage Trailer Supply can be either 1/8" or 5/32" diameter. We use 5/32" for almost everything, as the head is the same size as the originals. I would be very surprised if the holes are exactly 1/8 th offset everywhere, but if they are, you should use a scrap piece of aluminum on the inside as a "backer washer", then perhaps add another row though virgin material.
