Thanks for the replies. I was busy all day so I'm just getting back on the computer. Thanks for helping me ID parts and this will really help when I go to order parts. As far the as underside being clean, I scraped a 5 gallon bucket of crud off the trans and transfer so it was leaking over the years. I can see where the Carter AVS wouldn't be great off road. When I took it apart it had two huge floats and one of them was way out of adjustment. I just cleaned all the passages out with carb cleaner and compressed air and reset the float specs. My son and I flushed the brakes lines and we were able to get the air out. I was surprised the wheel cylinder pistons weren't frozen up after all this time but what I flushed out looked very bad. I'm going to flush another bottle through then go from there because it looks like it's clearing up. I took it on a drive up and down the street a few times going pretty slow. It doesn't stop very well so I need to look into that. The auto trans is shifting into all gears and that's what I wanted to find out. It back firing like crazy when I accelerate. I need to check the timing and vacuum advance and see it that's the problem. It seems to drive smooth and there was nothing sketchy when turning at slow speed. I found two buttons on the dash and I sure they are what activate the lockers. They must be air powered so I'm going to check this week and see if the air tank needs to be charged by the compressor to engage them. I think I should jack up the front and rear, engage the lockers and see if they lock. I don't think they are locked because there would have been hopping in the turn when I took my test drive on concrete. I have no experience with overdrives. Which direction should the shaft be, pulled out in pushed in for the overdrive to be activated? Where the t90 tranny stick used to be, they converted that into the overdrive selector. Radiator has a crack up near the hose outlet at the top. I'm going to JB weld it for the time being until I see if the water pump is still ok. My experience is the seals go bad and I'll address the whole cooling system when I change the pump. Mechanical fuel pump doesn't seem to keep up and I have to turn on the electric fuel pump. The dash has a fuel PSI gauge and it seems to run good at about 5 PSI. The oil pressure is 20 PSI at idle which seems fine.
