True. I didn't get around to calling the collision shop yet but I did some more searching online and did see there are solutions. It depends on the extent of the damage. My car isn't as bad as the cars you find in the salt belt so Im guessing mine wold be a little less expensive to fix. I did a little more research and found it was other z31 with the battery corrosion was bad as mine and they had just the frame rail replaced in that section with square tubing shaped and welded in place.

I like this next solution better. This person took the time to stencil out the pieces and welded them together. Click the link just below. I wish I knew this guy...

lastly I found online (see pics below) where someone replaced the entire bottom half of a 240Z. I guess this would be the solution to someone that has extensive damage that lives in the salt belt.

So Yes, It can be done. I just got to get the estimate.

Man, sounds like you found some great resources. I'd say if you have the time (sounds like this isn't your commuter car or anything), money, and space to do it, go for it! Looks like an exciting project. Would love to see pics and hear about the process.
