rear spring bushing size
 

I bought my '92 XJ and it already had 4.5" springs in front and 4" springs in the rear. "Supposedly" (and unfortunately I have no way to confirm) all of it came from Rusty's. My rear spring bushings are worn out and I'm trying to find some replacements, and OEM do not fit. I tried calling Rusty's and the chic that I spoke with seemed reluctant to help and said that she'd "have to get back with me". Even though that was only a couple of hours ago, I'm impatient and trying to find some replacement bushings, so I thought I'd see if anyone here can help. It looks like the bushing outside diameters are 1 13/16" and 1 5/16". Does anyone know if those dimensions sound correct for Rusty's springs? Or where I might be able to find replacements if they're NOT Rusty's? I've tried Energy Suspensions and no luck there either.
