If by Jr Series, you mean the Jr Gent II & the Jr Statesman, then you should be good to go. But the Jr Gent I bushings are smaller, but will work with the Sedona, Baron, Orion, Rhinehart (I think), and probably a few others.The only bushings I have are for the Jr Series. I think were meant for the Jr Gents ( which they did fit fairly well ).
