Hi Steve...this looks to me like one of the repair/straightening items has
been done. A common approach to improving this area of the frame is to use
a 3" galvanized electrical conduit squeezed to an oval and slightly enlarge
the pass-through with it before welding it in place. This does increase
strength as well as blocking most water from entering the cruciform. As
mentioned earlier, still drill a hole in the center to relieve water that
will find a way in. Robin Young B9471769
Heres a picture which somewhat illustrates the issue. This car was listed on
ebay.
Notice the discoloration below the closer exhaust through and also on the
further one which may have welds as well. Is this a repair removing rusted
out sections ?
