I just pulled these off my Crewcab...about 2-3000 road miles on them. The Downsouth site lists these as compatible with Bronco/F-Series with 6"/2" lift (front/rear). Part numbers and extended/collapsed measurements below.
Front Shocks:
#24-065283
21.52" extended / 13.27" collapsed
Rear Shocks:
#24-185530
26.16" extended / 16.14" collapsed
Asking price is $240 for all 4 shocks, and they're located in San Diego for local pickup. I can ship if you cover the cost, shouldn't be too bad within CA.
