Answer
Hi Mack,
That's a new one on me.

Did you disconnect the battery?

I guess it's possible the ECM has something built into it to prevent odometer changing, but I haven't heard of it.

Could you swap fuel guages?

Do you have access to the ECM from the cluster doner truck? Might temporarily swap them just to see.

Another thing I would suggest is go to a Chevy lovers forum I belong to, and ask the question there. I am Fixitfox33 on that site, and here is a link that will walk you through signing in.
It's all free, and a great site. Here is a referral link.

Chevytech would be a good person to answer that. He is a service manager at some dealership, and very knowledgeable.
But just ask the question in the 88-98 Full Size Truck section.  http://www.chevytalk.org/fusionbb/showforum.php?fid/78/keyword/1988-1998_Chevy_T...

I'll be watching for the question and answer.
