[TR] TR3 to Spitfire: gas tank interchangable?

[Paul Dorsey]

I have just bought a Spitfire (62-70 Mkl-Mklll) fuel tank for only $15 off
Ebay.  It seems the dimensions are similar to my TR3's tank size.  One guy
said he thought they were interchangable.  Is this true?
    I had needed to 'JB Weld' some of the fittings on my original that I
messed up and I thought this might be a good backup.

Thanks, Paul Dorsey
