It had never been off road but was showing signs of cracking and distorsion around the hole and the framehead was twisted. That part of the tunnel is really all that supports the frame-head as there's very little strength in the floorpans etc. Not too bad on a full bodied Beetle but it could leave a 'glass Buggy very weak.
Just my two cent's worth though...
Ahhh ok you think I just cut a hole in there. I guess you may think that as the pictures don't really show it clearly.
I added a CFAB Tunnel Inspection Plate Kit which is a 3mm rolled gusset and 2mm alloy cover plate. I have found this removes any issues with the tunnel and cracking.
