I have a first gen. 2dr 2wd blazer that needs a rear sway bar, do I have to get one off a 2 dr or 4 dr 2wd the 4 drs I've seen have the bar bolting rearward .

 

if i remember right,its a 4wd 2 door you need it from. 97ish plus. i got one outside for a while. just cant remember what it came off of.

 

I own a 1st gen S-10 2WD Blazer as well.

I used a 2nd gen Blazer ZR2 rear sway bar on my Blazer.
I used all the ZR2 sway bar links, U-bolts and bushings, however, in order to attach the links to the chassis, I used a set of frame cups from 1977-1981 Z28 Camaros for their rear sway bar set-ups.

 

Let me see if I can offer photo of my rear sway bar set up for you.
