88 k1500 guage cluster swap question

[wildfinger]

I just got done swapping out the 10 bolt for a 14 bolt SF with 4.10 gears and my speedo is way off. A friend gave me a guage cluster from a truck with 4.10 factory gears, but its for a manual transmission and my truck is auto. Swapping over the (PRND21) guage looks easy enough. But will I have any other issues? Will it cause any problems with cruise control? There is also a shift light on the new cluster will that affect anything?

Swapping the guage cluster will do nothing for your problem, you'll need to match the speedo gears or speed sensor to the rear gears. good luck.

has instructions to add a drac for future wheel or gear changes

88-91 Chevy's have the drac built into the cluster, so swapping the Guage cluster will fix my speedo.

Or you could change the jumper configuration on your cluster. I got the info from this thread, but it looks like the pics are gone now.
