Glad this got bumped, because I need it. The guy that built my Duster was a pretty good wrench...but a Chevy guy and totally unfamiliar with Mopars. As such, he made some...interesting...part selections. I'm 99% sure I have a JS front swaybar, with probably-original .85" bars on the otherwise-totally-rebuilt (PST) front end. (Car is a factory 318.) He coupled this with Super Stock rear springs, too-short underride traction bars, and HD shocks...with the result the front is way soft, and the rear is like a hardtail Harley. :BangHead: Obviously, most of this has to be dealt with.

Though a big-bumper car, my Duster is relatively light (~3300), with a 4-speed and no power options. I was thinking .99" bars (184lb), but this thread has me thinking I might want the 1.04" or even 1.09" MP bars.

Also, I dug up the old tech article about wheel rates from Mopar Action. For 35.8" A-body bars, the rates are...

.81 (MP drag)-82
.83 (slant)-92
.85 (315)-101 (No wonder mine handles like a marshmallow.)
.87 (340)-109
.89 (B/RB)-120
.92 (MP HD)-137
.94 (76 police)-149
.99 (MP)-184
1.04 (MP "HD solo")-224
1.09 (MP circle track)-270
1.14 (MP circle track)-323(!)
