I don't have any help to answer your question, but I have some questions myself on the same subject. BMR lists their swaybars to fit only 91-96. Everybody else who makes sway bars lists them to fit 77-96. The factory sway bars are interchangeable from 77-96.
So, my question is, "do the BMR swaybars fit all years or have they done something special to them to limit them to 91-96 only?
