It's the two small bolts at the front of the tank where the straps hook into the body. The space between there and the muffler is very tight. It was difficult to get them out and impossible to get them back in. Using a pry bar, I can barely get the muffler to move, not enough to get the bolt in. I'm sure that 1/4" shorter bolt will do the trick if I can find one.

Gotcha. Yeah, you can use a sheet metal screw, but might have to make the hole slightly larger. But if you use a sheet metal screw, you can get any length you want. And I have no idea why they include such long ones, I just ended up using OE repop ones.

As for the standpipe, your' car should have one, it's at the top of the diff hump, and can be seen in the trunk. It's behind the back seat. '70 I think is the only year that didn't have them. (pic)

I have an aluminum cover on my 12 bolt, and my pump extensions are about as far as they can go, and allow the 90 degree fitting to not get whacked off by the rear cycling up & down. (pic)

If you get stuck not having ANY room, bending hard lines is the way to go. You can follow the OE line path, and think some cars even have a brace at the side that screws into the stamped seam of the tank. You could use a piece of flat bar stock, dipped adel clamps, and mount it on that seam too.

EDIT: Don't drill on the inside of that stamping of the tank flange/seam.

I haven't noticed it but I'll look for it next time I'm out there. That would be great if I have it.

If you don't have it, see if it has the provision for the standpipe and if it just has a block off plate.

70 was kind of a transition year, I know 71-up had them. If you have a late 70 production, I suspect it has one.

You will know if you look. And from under the car, all you see is the line ends sticking thru from the trunk.
