A very big welcome Ken!
Your car is sort of a CHP Mustang celebrity:
Mike M. should verify this but from the info I have your car went into service on 8/7/90 and was stationed at Banning.
It may also be one of the cars in the top photo of this cover:
Does anyone here have this issue? If so, can they check to see if it mentions where the cover photo cars were from? I thought I heard somewhere that they were from the Banning area.
I'm curious about what condition your car is currently in and if you have any photos you can share? I've always hoped that this particular car would surface someday and be in good hands. Sounds like it is and if you're into SSP preservation Ken, you'll find plenty of help here!
