is this the right part number?

[DaUsedMCR]

im looking for the oem ACDelco exhaust manifold gaskets. ACDelco and RockAuto say the part number is 12617944, but part finders on Amazon and Ebay say it won't fit my 2001 Tahoe 5.3. Is that the right part number? are they the same number for both the right and left sides? thanks!

That is the part # 12617944 I was given when I bought from Dealership.
I found this info online for you.

This is the factory replacement exhaust gasket for most V8 LS applications since 1997 -- fits LS1, LS2, LS3, L76, and L92 applications. Not designed to fit the stock exhaust manifolds for the 2001 thru 2004 LS1 or LS6 Corvette - these apllications use GM gasket part number 12576221.
The large round design of this gasket #12617944, will fit most aftermarket header applications and the GM stamped steel design provides excellent sealing capabilities for the most severe applications.

Dimensions:
Diameter = 1.870"
