Cal, if you are going to run the Cold Case let me suggest you do several things: First, ditch the O-ring for the Renix sensor in the tank. There is no support for the outside of the O-ring. It will blow out. Either put in a metal backed seal, a soft aluminum washer seal or just seal the plug directly to the tank.
Secondly, flush the radiator several times before you install it. These radiators are full of metal shavings. I expect they are the product of cutting the cores. I wouldn't be surprised if they are the reason so many Mishimotos end up being plugged.
Finally, expect to need to re-seal the overflow fitting at the radiator cap. Whoever is assembling these things must be racing a work quota. They only thread them in a few turns.
Beyond those things, don't expect to fit a ZJ clutch. I found installation went smoother if I improved the chamfer on the pins that drop into the radiator support at the bottom. I also ditched the drain ****. Planning ahead and ordering an aluminum plug (3/8 NPT IIRC) might be best.
And it may be that you already know the above from my own posts on the topic, but the info may be useful to someone else.
Edit to add: Somehow I never before noticed that we have nanny control software. Make that a "drain rooster", or maybe "draincock" will sneak by...
