Hee is my install of the blazer tank it came out pretty good, and I did it for a completely different reason, I needed more room in the cab for my fat "mule" here is how we did it. Kieth

1. mounted the flange under the frame , welded 4 bolts to the top of the bottom frame flange to make it easier to take in and out.
