I have two off a 69 Chevelle, with the markings NL on them. The L is on/over the N...Don't know if 1970 used that marking. No rust...off a Arizona car.

All 68-72 GM A-Bodies shared these.
Very Possibly more before & after.

I see these in Coffee Cans at swaps.
Try the Bone Yards too as they should still have them.
Even if the cars are long gone,look in the mud.
They are usually laying around after they remove the tanks before crushing.

The ones I have are at the rear of the tank/car and are very small sheetmetal type. Those look to be for the front at the axle.

Sorry,I considered those the back bolts.
Here is the bolt used to support the tank strap closest to the Rear bumper.
GM recognizes them as #399782.
Measures 3/8 X 15/16 with an "E" in the center.
I believe www.paragon-corvette.com (http://www.corvette-paragon.com) carries these.

That is what I have...although it has a few more threads...but not all the way to the head of the bolt.

You're right.I went & removed the ones from my Chevelle & found that shoulder bolt too along with the L over the N.
Donnie what head marking is on yours?
