Could you help me think through possible changes in front sway bar geometry, which may be made by substituting aftermarket poly sway bar mounts and end links?

You see, the Summit Racing catalog was open and the Visa card lay there before me, so I ordered some polyurethane sway bar mounts (Energy Suspension; 13/16" approx. = 21 mm) and sway bar end links (Prothane).

Then I removed the front sway bar. After 110k miles the bushings were pretty banged up. This removal:

1. Turns the car into a 1969 Chevvy for handling

2. Reveals that the new toys may not work.

The new mounts are about 1" less tall than the stock Volvo. The goal is to keep stock geometry, right? I mean, Volvo did it for a reason, right? I don't yet see how to slip the poly bushings into the old mounts (though I am looking at the bandsaw out of the corner of my eye), and am considering mounting 1" blocks under the new poly mounts to bring them to the stock location. (Am also considering putting things back the way they were!)

And the end links. Got the wrong length. (Tip: length is, reasonably enough, measured as distance between the nearest metal points on items to be linked; not overall length of link, nor length in the middle, between where the bushings are. Duh!) Even with the right length would poly, doughnut-shaped bushings work? The package tersely says to mount the links between parallel surfaces. But the Volvo's existing end links are pretty well canted, forming a kind of parallelogram. It must be obvious: the poly won't deform to accomodate this skewing, right?

Thanks for your help! Gregg
