[GMC-YA68]

Went back down to LMC and looked at their 31 gallon. This one had a fuel bowl/baffle so I grabbed it and installed it tonight. I used the old rear crossmember from my other frame for the front bracket. Moved the original rear bracket back a bit. Snugged the straps and it fit like a glove. FYI - The new front (old rear) crossmember was notched at one time to fit the old 38 gallon Aero tank. That's why you can see the old notches if you look closely.

Edit: Oh and I used spacers on the front crossmember because the frame gap was wider. Plus fitting both crossmembers so tight together I was able to snug the tank up between them fairly tight. The flange of the tank sits about 1" lower from my frame and sits very even this way. Any higher and I would be worried about the body sitting on the fuel neck. We'll see when it comes that time I guess.
