I have a rebodied 84 4speed, and wanted to ask is it worth $50 more for the solid cradle bushings over the poly for a car that will only get an occasional summer cruise?

Less to wear out but possibly more engine noise in the cab and vibration.

poly is a waste of time .why the engine cradle has rubber mounts is beyond me .you can not hear any extra road noise with the solid mounts vs poly. i have had both on my car . the noise you hear is the same because all your suspension mounts are rubber (or poly if you have switched them too) . the 88's came from the factory with solidly mounted cradles .

Personally, I think the solid cradle bushings are worth the price premium. But I may be a little biased. My '87 Fiero has had solid aluminum cradle bushings since 2004.

i disagree, the vibration is noticeably less with poly bushinsg vs solid, but the ride is still more stiff than stock rubber... just my opinion

Solid may provide a bit more vibration, but will eliminate sloppy cradle movement in corners.
