How hard is it to replace Idler Bushings on a 124?

I ordered a bushing kit, and a new stabalizer after my
"drift" at speed was traced to play in the idler arm.

What kind of difficulty can I expect? I have read in the
123s had to have the exhaust dropped (?!?) and am hoping
the 124's are not so involved.

Thanks,
