Update, fixed the sending unit. Seems it was working fine but the brass float had a hole in it. Safety wired the stock diesel plastic one to it and it's all good now. I was think of tack welding them together, but the chance of fire seemed pretty high.......
Also figured out why it would only pull fuel above half a tank. Put the pick up extension on the wrong tube....... The Bronco sending unit with the in tank pump had 2 tubes in addition to the return. It only took a second to realize that I had picked to one that went nowhere for the extension.........
Then it was time to figure out why I had no parking brake and what the growling was coming from the D-side rear drum......... As I was beat uselessly at the drum trying to free it I happened to be looking at the leaf pack. Odd, there seems to be a notch in the main leaf. As I bent down to get a better look I noticed I could see all the way through it. Cool! So I went a picked up these.
After fighting the u-bolts for about 30 MIN I decided to cut them off and replace them. Napa didn't have any replacements on hand and it would be 28$EA and 2 days to get them. So I reused the stockers after a good wire wheeling and left out the overload spring to make them long enough.
While attempting to get the springs out I realized I couldn't get the shackle bolt out with the service bed on it. So I drilled a hole in the service bed to get to it......... The nut promptly rounded off. It was at that point that I determined the springs would have to be cut off and that project was going to wait till the service bed was gone. So I welded the stock spring back together and bolted everything back up minus the overload spring due to the newly shortened U-bolts.
So now that thats all sorted out and I replaced all the missing brake parts, it's time to build radius arms and mounts for these.
