Finally got the overheating problem under control. Had to flush the radiator several times to get the many years of accumulated junk out of the block. Of course sitting for 38 years didn't help either. Had truck up to 54 MPH yesterday...I think think engine really likes this transmission. Also turn 100 miles since getting it running. Hey it;s a milestone! Used my GPS unit to verify the speed and miles because the speedo is a little off. Installed a flip-up license plate bracket to hide the hitch receiver and working on new tailgate supports. They will either be cables or the older flat pivoting bar style. In the meantime, I decided to try a different seat. Found a 3rd row bench out of an Astro van. Fits real nice..working on mounting brackets. The leg room is tremendously better! May recover the door panels to a lighter color!
