Not sure if you mean you want to buy some double adjustables or need information on who makes double adjustables.
Basically, if you want to buy double adjustables, you are probably going to need to buy new since there are very few SRT-4 users of double adjustables and coicendetantly very few makers of double adjustables. If you can get some used (and in good shape), count yourself lucky.
As far as who makes them, there are really only three that I know about (without going custom).
1) BC - just came out with them so I don't believe anyone has really tried them yet
2) Mopar Stage 3r - I will let others chime in on using these since they are probably the most used among srt-4 owners who track there car
3) Motons - Very good (from what I have heard) and very expensive
