Mopar did make one.... More than likely you will not find one, unless you know a guy that knows a guy that is working in some obscure corner of a wearhouse, somewhere in the land of lost socks and missing remote controls.... The following might help though, I got it from the "Pit Stop" section, in the back of the Dec. '03 Hot Rod magazine.... According to the author, the kit contained:
"Referenced Chrysler/Dodge/Plymouth minivan parts are from models with five-stud, 4.5 inch bolt-circle wheels. Do not use parts from '84-85 with four-stud, 4.0 inch wheels, or those from '87-90 five-stud, 4.0 inch bolt circle wheels. Caliper design (1 or 2 pin) must be used with the correct corresponding hub and knuckle."

Hurdles appear to be, the minivan springs possibly being too weak (try custom ones), the k-member (mopar performance) isn't available anymore (bottom has to be cut out of a daytona piece, to fit the v-8 (looks like oilpan clearance, from the pics), and the wheels end up sticking out too far (either relocate the daytona control arms inboard, or cut and narrow the arms). Also, from the pics in the article, it looks like the spindles are flipped around, so that the tie-rods connect in the front, rather than the back.
And that's about all I know about that (so far).
