you can reenforce the lower arm with plates either made or available from a few suppliers, and then install a spherical bearing in place of the old bushing. that is what i plan to do. at the same time you should consider replacing the strut rod bushing with a rod end to eliminate all bind in the front suspension.
Yeah, I plan on the strut rod too. How would I install the spherical bearing? What would hold it in and where would I get one?
After disassembling the suspension and feeling how stiff the perch was, I think this is a must do mod now.
PM opentracker, he can give you all the details on how to do the lower arms and he may even have a template left for the weld in plates. you might also consider a set of his roller bearing spring perches. then i would look at a set of street or track adjustable strut rods.
