I have a '62 and was told by LMC that these models have the X frame which results in a different configuration than the later models, hence the tank you are looking at won't fit. That being said, I have read that these later model tanks will fit, it's just that the mounting hardware won't fit and has to be fabricated. There are a lot of outfits that will build a custom tank for you for $$$$$$$'s, but I have yet to see one in an aftermarket catalog at a decent price. If I ever change mine, (I am currnetly using the original cab mounted tank with fuel injection lines), I will just do some measuring and go to the junk yard for a Blazer tank. But I then have to find a place for the spare, thus that project is on hold.
