[TR] TR3 Rear Apron & Bumperette mounting

[Bill Beecher]

Starting to put the repaired body back together in prep for the final coats
of paint and I am just now coming to the realization that the long
tubes/bushings that the rear bumperette bracket bolts go through are
probably permanently attached to the rear apron.  Of course, when I took the
car apart these came loose freely as I disassembled everything.
 
So, If I need to go back and weld these in place, can someone tell me how
much of the tube should protrude past the sheet metal of the rear apron...
Or should it be flush?
 
Thanks,
