Instrument cluster for 91 S10 Pickup

I bought an instrument cluster (not digital) off of eBay for my S!) pickup that came out of a S10 blazer. It installed OK but the temp/ speedo/ and fule gauges are off somewhat. The blazer part number is 25087904 - the question is: are these clusters interchangeable (the blazer and pickup)?

Does anyone have the part number for a 91 S10 pickup instrument cluster?

Thanks!
