91 saggy butt shims and one unit spring perch and strut top

[chochocho]

hello all,

i am looking into getting those saggy butt shims for the rear of my 91 ss. it has the one unit strut top and perch.

i plan on ordering some extender nuts so that i can install my rear strut bar. does the rear strut top/perch allow for it?

thanks in advance.

I have the 1" thick shims, and I was able to get the bolts snug to the studs without any issue. If you add a strut bar, you probably won't have an issue. It seems like there was still enough of the studs sticking out.
Also, I used a tile cutting bit on a router to zip out the holes, and shape the shims to the shape of the 91 tophats. I'm not even sure which ones I ordered, but the holes weren't even close.
