I'm in the process of restoring a 58 TR3A and with the fenders off, there is a big hole almost 8" across and looks to be factory cut in the passenger right side foot well. It looks like a great place for water to get in. What is it for and should I seal it up? Thanks Larry Miceli Mount Dora, Fla 58 TR3A 73 STAG 74 TR6 Sent from my Verizon Wireless BlackBerry
