UCA Bushings don't fit?

Do you know if your original bushings included the little end caps? I don't know if 69 model is supposed to have those or not. I know if you picked them off the arms would fit the chassis clips.
The piece of tubing inside the bushing would butt up against the oval bolt slot. The end caps change the bite but change the spacing also. You might look closely at the chassis clips and see where the original bite was.
You might find it interesting to learn... When Moogs offset bushings first came onto the market, they did not include end caps. Today we find custom made caps with offset to match that bushing in the box.
