In mine, I installed a late model square body Suburban tank which is deeper than a Blazer tank. It's a 4x4 so it's ok. A lowered vehicle it might be a little low.

I had to relocated the rear frame crossmember to the very back and purchased another from Richard which I installed closer to the rear axle. This gave me the two attachment points for the square body straps.

I had to heat and re-angle the filler neck. The diameter was also slightly different than the OE and I had to make an adapter.
