The 88+ C/K truck version (new body style) might of come with the 6 digit Odometer however, the R/V version (old body style) remained 5 digits through 1989.

In 1990 and 1991 R/V's (suburbans and full size Blazers), changed over to the 6 digit Odometer and it was now controlled electronically. My 89' had the cable driven speedo and I converted it from the 5 digit to the 6 digit. A lot of work but the results were great!

The 2 shaft radio's in the R/V version also remained through 1988. In 1989, they switched over to the larger, square radio.
