I've been shopping for a new tank as well, so if you find a source for your TF panel post it here, they may have AD underfloor tanks. I've gone to several shops and asked what other years/models/makes will fit, nobody has a clue. Apparently, you can't just give the dimensions, capacity, and porting requirements to find a similar tank. Not sure why this is, probably has to do with Google replacing the pre-frontal cortex of today's mechanic. Short of having my tank purged and welded the most cost-effective option I've run across are plastic marine-application fuel tanks and fabricating my own straps.
