Even if tubes are installed, you will have no idea how bad the corrosion is under the ribs. The ribs must be removed to inspect and clean out corrosion. I have a set of barrels with a hole in one bore that goes all the way to a corresponding hole in the opposite bore. How bad is the corrosion under my ribs? Very bad, I would assume. I would love to find someone who would agree to weld my barrels to close those holes, but I'm not holding my breath. I assume your corrosion resulted from the unprofessional refinish that was done by the fellow who drilled that weep hole but didn't know how to purge the moisture before sealing the hole. You might find someone who can sell you a set of Trojan barrels. Are your barrels with or without the extension rib?
