Reaction strut bushings are place I would consider poly
But then strut rod placement must be checked and if needed, bushing thickness modified.
Otherwise you may find the LCA being pushed back (or forward) from its proper position - especially when using nylon or poly LCA bushings.
I understand the concept of what you're saying. If it doesn't take this thread too far into the weeds, can you describe how strut rod placement is checked?
Sure. I made a webpage about it long ago. It was particulalry an issue with the poly strut bushings when used on A-bodies, or at least the a-bodies with the earlier struts.
Basically I test fit the LCA and strut assembly without the strut bushings.
With no bushings, then measurements could be made for reference. This is the position of the strut relative to the K frame where the strut and LCA are not being pushed back (or forward).
Prob best to have the LCA at a somewhat horizontal position (representing typical ride ht) not hanging down.
