UPDATE, I purchased this to put into my 91 77 series, and it does not fit not even close, the 77 series come with a compartment that hangs down to store tools and whatever, this tank is clearly made for ones without the cubby. Newer 70 series wagons, I believe 2000s stopped having the cubby, and that is what this tank is made for. Sucks for me. Beware these tanks are made for the newer style wagons. For what its worth they are indeed made well and I wish it would have worked for me. Since I have it now, and highly doubt can re-sell it I might try to modify it to make it work, but it will take some serious fab work. Stay tuned
