Shocks for '06 Dyna

I know the 06's have a new frame, but does anyone know whether the shock length, springing, mounting bolts, or anything else is different? Neither Progressive nor Works can tell me they have a shock to fit my '06 Superglide. In the MoCo catalog there are different listings for short shocks for 99-05 and 06, which would seem to indicate something has changed. I don't want short shocks, just better ones, but no one seems to know if shocks made for "older" Dynas will fit. The stock ones appear to be the same 12.6" eye-to-eye as before, but beyond that I can't tell what may have changed.
