drill 8 times...

and the holes still don't line up.

It took some time attach the 4 coupler plates.  I made the holes in the plates 0.185  and the holes in the end frame 0.171.   The rivets are 0.184 in diameter.  so I had to grind them down to 0.173 for the frame.

The next step is to weld it all together.  But the question is, how do I do it and keep the pedestals in alignment and square to each other.  I am thinking I will need to make a fixture to hold the pedestals while the frame is welded.
