That is all there is to it from what I remember. The firewall may need to come out first, I don't remember if the tank is under or over the lip on the top of the firewall. But those clamps you see on the sides do hold the "tank" in. Across the top of the cowl to the brace under the windshield, I don't remember for sure but I don't believe there are any bolts there. But there could be, this is all super easy stuff, and fun. So just take your time and remove the bolts you see and if it doesn't come out look for more bolts. It's all good, and it isn't hard to figure these cars out, that's the fun part.
