strut rod bushings?

Look on rockauto at the one called "improved design". I used that on my 65 Dart (or maybe from Energy Suspension, I forgot). What they sent you looks similar, but not exactly. While the original was the 1-piece design shown above, I don't like it. Not only is it very hard to squeeze the rubber thru the hole, the rubber is quickly cut by the frame, in my experience. I got the PST kit for my 69 Dart in early 90's and it had the 1-piece type, so looks like they improved.

My "improved kit" had 2 indentical hard rubber (polyurethane?) parts with steps that fit in the frame hole, a steel collar thru them as shown, and the 2 curved washers on the outside. I don't recall the "centering collar" shown. Maybe that drawing is for AMC. I similarly did my 65 Newport. It was slightly different in that the 2 rubber pieces were different with one having a step that fit into a recess in the other.

Don't quote me, but I recall that both curved washers should bend away from the frame, which seems counter-intuitive. Without a manual, most people would think they should cup over the rubber bushings as the one on the right is shown (incorrectly?). I think the outward curve is to allow free pivoting as the strut angle changes. I imagine it would work fine if you used a flat washer, but it should be the same thickness. Also, don't try too hard torquing the nuts to expose the cotter pin hole (I think the Dart has one). I couldn't get to it, and stopped since one FABO guy broke his strut that way. After a few years wear, I'll tighten the nuts more and see if the hole appears.
