google GM RPO codes and youl find the answer, this will tell you what every single code on that tag means.
B4U - performance package, sport
9c1 - SEO vehicle, police car

Highway gears pretty much, all B4U's came with them with the trailer tow package. 9C1 rear ends were 3.08's with disc brakes in the rear, where you have drums
yeah have the heavy duty trailer tow package sticker in the trunk
