Issue with Expansion Tank

The "spacer" is a part of every expansion tank assembly. It is silver soldered to the tube to the tank when it is constructed.

Without seeing what is causing the interference it is hard to say what the problem is. Sometimes the distributer needs to be rotated because a holddown clip or other obstruction on one side or the other of the distributer is hitting the tank. It is a snug fit under the best of circumstances.

Well that answers that. BTW, my #2 spark plug boot does just barely touch my expansion tank.

Okay, I think I found the problem. Take a look at this photo:

Notice the difference in the angle of the plate and the mounting ring? if the ring was flush with the plate it would be at an angle where the tank would not interfere with the distributor.

Here is a close-up view:

Can the tub be bent so that the ring angle will align with the plate, or would that damage something? Just looks like a sloppy job putting the thing together. I really wish people would take more pride in their workmanship.

Your pics did not get posted properly.

I don't know whether you can bend it or not, but I will tell you the technique I use in circumstances like that. I just go ahead and try and bend it; if it brakes, it needed replacing anyway since it wouldn't work without bending it to begin with. That theory has worked well over the last 35 years or so... but I've replaced a lot of parts.
