Energy Suspension doesn't list individual S13 bushings like they do for S14 and Z32 (in certain cases)

I need rear suspension bushing for the Z32 uprights, will the additional bushings work on the inboard sides of my few remaining stock links?

I also need front LCA bushings. ES lists LCA bushing separate from their sets... any critical difference between S13 and S14 control arms at the bushing end?

I know I could call ES, but I figured SOMEBODY on here has tried this before...

Thanks
Dan
