Friday, the guy who runs a Porsche and air-cooled VW resto shop looks at my '70 /4 and pronounces it v. nice . BUT it does have some rust perforations on the pan. The inside floors are solid. I expected (anticipated and kinda wanted) him to say that a whole new floor pan was warranted. He said that except for the affected areas (2 spots about 9" long and maybe 1.5" wide) the rest of the bottom was solid and needn't be replaced. His suggestion was to splice in new metal from repro pan sections, leaving most of the original pan intact. This shop comes recommended by some long time friends who have 356s and early 911s. This place isn't cheap and I've seen his work, and it's nice and thorough.
I'm hoping you won't tell me to do it myself, 'cause after working 10-12 hour days and weekends, there really isn't a whole lot of time(and energy) left to . After 30+ years with this car, my approach is to throw money at the problem
At any rate, whaddaya think? Full pan, or settle for "patchwork"?
