Me too!  I don't know what your van's problem is, maybe DPO reassembled things wrong somehow?

  Mine go as far past 90 as I want them to.  On both the 87 syncro and 84
  2wd.  Hmmm.  Seems odd to have a stop there, the point IMO is to scoop tons
  of air and hurl it into the van.  They stay open way past 90 degrees until I
  hit about 45-50 MPH.
