Since I had to be awake at 2am for my EEG test prep, I figured I would put some time in on his car.
Over the last week I cut the glass packs out. they were rusted through. The rest of the exhaust had no issues. I put straight pipes in place of the glass packs, added a cross over, straightened the system up and welded all of the joints. They had the cheap band clamps with the pipes butted to each other. Leaks at every joint. Whoever put this system in, obviously, did not own a welder. Maybe that is a good thing. The whole system drops out as one piece, so welding was easy. Made a couple of tacking clamps out of the junk clamps.
Put the new battery in this morning and added a battery shut of for when it is not driven.

A discerning eye will see that I already shorted it

while checking for tight when I was done.
Adjusted the shift linkage. It was a nightmare getting it out of reverse. So I sat and read how to adjust it. Drivers' seat and the consul had to come out. Made the alignment tool. When the clutch was changed, this adjustment was not done when the transmission went back in. It should not have been needed, but I could see that the adjuster nuts had wrenches on them not to long ago. So the tech took too much apart. All better now.
Pulled the parking brake mechanism out. Cleaned and lubed, so now it works.
I do not think there is anything left to fix. If a food trailer was not in the way, I would take to find breakfast. But it is cold out and I do not want to run the forklift around outside.
