Got back home late last night and spent a couple hours in the garage continuing the tear down of the T top car. Got the radiator and front end removed. Found confirmation of a front end collision in the top rails - both are somewhat buckled.
Pulled the buck tag off as well:
Pulled the cribs from under the table then lifted the Cobra onto them. Got the new dipstick and coolant sensor installed. Now the fan kicks on as it should and the handheld keeps up with my gauge, so all is good there now. I'll most likely take it off the cribs tomorrow and take it out for a drive to let the system self learn a little more. I think I'm going to put the braces on hold until I get the rockers and floor pans replaced. I crawled around under it again after I got it lifted, there's a small problem area on the passenger side floor at the front seat rear mount along the rocker seam. Between that and the rust showing it's ugly side on the rockers, it's time to get them taken care of before I get crazy with some of this other stuff. So the plan is to get the T top car stripped down so I can dispose of the shell, then turn my attention to tearing the Cobra down for it's surgeries and additions.
