Just one of the fans is enough to keep my truck cool, i bought a wiring kit from advanced and wired it and attached it to radiator. It was very simple. I have the second fan currently wired to a switch, b/c I don't have a/c wired up b/c of bad compressor, just in case but havn't had to use it yet.

Also, I haven't torn down my 87 yet. I want to have everything running like it should on the 01 chassis before I tear down the 87. I still need my truck so I can't afford too much down time. Once everything is running great and I have all the parts then I will start pulling stuff apart!

Will you be using the original dash cluster from the 87 in your swap? I wouldnt mind having one like that for my 1 ton

My plan is to swap in the cluster from the 2001.

I call dibs on your old cluster if you decide to not use it. Hit me up if you decide to get rid of it. I may swap in a NV4500 in my 1 ton and that dash cluster would be nice to have.

Haha, we will see. Im assuming you just want it for the tach I swapped in out of a earlier model truck. That tach was hard to come by!! If my friend who has a square body doesn't get it, I will remember you. Thanks for your interest.

Getting the dash apart and labeling all the wiring!! Still a ways to go, I think I accidentally tore the cover over the pass air bag. Dang.



So far the plan with trans is to flush all fluid and put in new and new filter and see how it does...


Sat the dash cover from the 01 into the 87... It could work... May check into it... Not sure yet. Opinions?

I believe people have done it before.

I haven't seen anyone do the 99+ style.. I've seen a few guys attempt the 97 style dash but never really any fully finished stuff with good pics.

I'm more so interested if anyone's ever swapped the under dash ac boxfromthr nbs (withservos) into square body n replaced the vacuum setup. A lot to consider here and a lot of neat things could done. However, I don't mind the 87 dash, kinda gotten used to it but I want to make this swap as clean and neat as possible.
