This can be a cool Option to have is off the 1988-89 Surburban / Blazer Reg Speedo W/Trip if they had the option. But can be found in the 1988 - 1991 Surburban / Blazer if they had the option for the trip but the 90-91 most have the electric speedo sealed. So the break down it have a Reg speedo would be 88-89 w/ reg speedo w/trip Surburban / Blazer. If your got the Speedo 87-up with electrical module the you better w/ the 90-91 most of them will be electrical module speedo and if they have the speedo w/trip option.
