what do you use to clean the frame before you paint?
I can't remember the name for sure. I got the info for it off of pirate4x4 forum. I bought it at Lowe's comes in a quart type can or in spray on I used it boths ways it worked AMAZING! They claim you can let it sit then power wash it off.
I was afraid that stuff would fly all over and get on my cab and I would have a spotted truck. I will find the name of it and post it up for ya.
That fuel tank....did you have to remove that large crossmember that holds the spare tire up or does it simply bolt up to it with straps?
I originally planned to just strap it up against that stamped steel crossmember you are talking about that holds the spare tire. After I got the tank and test fitted it up I feel it hangs a little to low.
After the rear spring brackets are welded on ( waiting on them atm) and the leafs are bolted to the axle and the truck can hold itself up. I will then take those huge ass stands out of the back. I plan to weld some temp cross peieces in front of that cross member and behind top and bottom. Then I plan to fab a new cross member out 1/4" wall 2"x2" tube. I plan to make it wider than the tank. Then have cross pieces to support the tank.
I will post up some pics for anyone thinking of doing the same thing so they can see how it turns out. Should be plenty of room for the rear pig to clear it even being it is a short bed.
I will see if I cant draw up a rough looking pic with paint of what I plan to make see what you guys think. Should be stronger than that stock cross member and allow the tank to move up about 4".
