Paul,  it is difficult to fit 1" dia tubing to a 9/16 o.d. weld
bushing ( although the reverse is no problem).   It is even more
difficult when the two are joining at very low angles which is the
norm with the S-beam especially the tubes that go to the lower
corners of the firewall.   One solution would be to make the bushing
1" o.d. as well. Inserts welded in the ends of tube could be drilled
for the 3/8" bolt. The insert would be 3/8 or 1/2 inches wide. What
do  you think?                 Jerry


Let me get things straight here.
Are the lower tubes are one inch in diameter?

What is a weld bushing?

I think I need a better picture. Can you make a old fashioned 3 view drawing?

Your drawing looks like a rear motor mount tube with bushing
tapped for rod ends.

I am not following you.
