Those are the anchor bolts for the straps that hold your gas tank, should be
two more like it in the trunk just on the gas tank side of the rear

I am no roll-bar expert, and hopefully someone will chime in here, but I
should think that you would go all the way through to the frame to anchor it

Long time, no see.

I am installing an adjustable rollbar on my 60 TR3A.  'Adjustable' because I
don't really know where on the back shelf to position and mount it.  It's
heavy (schedule 40) and narrow and by 'trial' mounting it thisway I'll be
able to decide it's position and heighth.  I used 6 pieces of
particle-board-shelves (cheap and heavy) with 3 of them under the feet of
the rollbar and 3 immediatly on-top of the feet.  This seems to hold it
steady (mind you, I've not driven this car...yet!).  Of course, I need to
mount it to something.
     On the rear of the shelf and almost in the boot, is of course, the gas
tank.  On the front side of the tank are two brackets (pedestals) that hold
the tank up.  They are welded to the shelf, howesver, they also have a bolt
and welded nuts attached.  WHAT ARE THESE TWO BOLTS FOR?  They are 7/16"
fine thread.  These might temporaily anchor my adjustable rollbar.

Thanks, Paul Dorsey             60 TR3A
