Use new tanks and tank supports. Using old supports as a guide, put 3/8 X 1 bolts into each of the 4 bolt holes in each support assembly making sure the head of the bolt is towards the tank and tighten them up. Now weld the bolt head to the bracket and remove the nut. Next, again using the old tank\bracket assembly as a guide, assemble new tanks and brackets making sure to use some type of insulation between tank and bracket. Heavy roofing felt or tire tube will work fine. This makes installing the tank a 1 man operation with the bed off or on. PLEASE NOTE!! Front and rear supports are different!!! Before you weld anything up make absolutely sure they are in the correct locations and that the bolts you are going to weld in are in the right holes for your application. Also, the front bracket has 2 holes in it for the strap bolt\stud to go through!! Make sure you put yours in the same hole or the tank won't mount. I do believe tank supports are still available from GM. I got mine there 6 months ago. You would be well advised at this point to replace the senders too. It's cheap insurance. jim

Little stuff left to do is mount winch, wet sand & buff out and build belly pan\running boards. Body work takes lots and LOTS of beer!!!! God, Guts and Guns made America and God, Guts and Guns will preserve it! The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shotJim or Paladin whichever you choose.
