I'm in process of installing a set of Smart Tabs and removed the old hyrdofoil last night. I assume I should I fill the holes on the cav plate? Could I use some duct tape as a mold/dam to fill with JB weld then sand smooth? I assume it would stay in the hole depending on how much pressure the plate sees while in operation. <br /><br />also...<br />Does it matter if the upper bracket is mounted on the left or right side of the actuator? The brackets on the tabs force the mounting of the actuator to be on the left and I would like to mount the upper bracket opposite due to interference and was wondering if this would be OK?
