Gas tank replacement help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ok. The gas tank that was on my 1970 Jimmy when I bought it was all banged up and leaking from the inlet hose and the sending unit area, and the last time I drove it one of the straps that hold it on broke!

I got a replacement kit, and it only came with two j-bolts, but when I was taking the tank off, I noticed that the 7" squared u-bolt on the other side was in the wrong holes on the frame, so I was taking it off and it twisted the threads completely off and I can't find one of those ANYWHERE. I checked several auto parts stores, some hardware stores, and some spring shops that were supposed to be able to make custom equipment but nada. The only place I haven't checked yet is a junk yard, but I bet I'd find one just as ate up as mine was there.

I've been thinking of just using some regular bolts on it, and run a nut up it to hold it tight while tightening the nut on the strap. What I'm wondering about this is, typically when you cinch the straps up, doesn't it pull the edge of the tank flush up against the frame? Would having the extra nut in there holding the bolt be a problem since it wouldn't let the tank pull up flush?

On another note, I checked the thread about the curve in the stock metal inlet neck. I didn't realize it was brazed on and could be (or, was supposed to be) swapped to the new tank, so I went to a pipe & hose seller and got some reinforced fuel hose that I can bend around to how I want, although it won't retain shape (it's not flex hose), so I'm hoping that it will maintain and not get pinched on the body mount. Should I hold off and just go ahead and get the old curved neck put on the tank? Or, another thing I thought of is to cut the old neck off and use about a 6" piece of that hose to attach it to the neck stub on the new tank. In that thread though, someone said that would make it too long and it would hit the body mount. Any suggestions? Final thought on this is I was just going to try putting it on with the reinforced hose and hope it misses the body mount.

If anyone wants to see some pics, I can post them, just let me know.

Thanks for any help y'all can give me!
