What year is your truck?
If it's a 92-94 I'm fairly certain a 92-94 cluster with a tach already in it will work. ... Not to mention if it isn't set up for your tire size and gear ratio, it'll need to be reset and the kits are gone. There's a work around for that I think though.
I found a tach cluster for cheap that I am going to try. My truck is a 1993 work truck that came with a 305 V8. Along the way it acquired a 350 and of course I had the usual 200K mile transmission rebuild. It runs and drives fairly well.
I'll keep my fingers crossed on calibration and if it is off I will definitely be back for more advice. It has a fairly tall rear end on it so speedometer may be an issue. Thanks for your help.
