Mopar isn't making bars any more but you can sometimes find them on web sites and auction sites.

Talk to the guys at Firm Feel. They can recommend a nice combo of t-bars and s-bar for what you are after. They do make a .88 and offer a .94. The .88s with a 1.125 front sway bar wouldn't be awful for a street ride since that is close to a factory 383 size. Personally, I'd go with the bigger .94 rate for street driving plus it makes the car much more consistent on track day.
