help finding a part
 

I have an 86 190E (gas) with a 5spd, it is getting pretty difficult to get into 1st, 5th, and reverse. I contacted an online MB parts supplier and they sent me a list of the bushings they had, but shifter assembly is a little more complicated than the last stick that I owned and I am not quite sure what part I need, shy of ordering them all! Can anyone point me in the right direction?? Thanks
