Well, the VIN has been decoded. For those paying attention, this is the FIRST '88-'91 that compnine.com was able to decode for me. I've tried 5 or 6 others in those early years with zero results. '92-'98s are never a problem.
I think I may have asked you this before in another thread, but have you ever tried re-running those VINs since then? I seem to remember running one there years ago and not getting any results, but then I ran it again a few weeks later and it popped up.
