Got back to working on the body bushings on the wagon. Picked up an M12-1.50 tap and stuck it into a 9/32" 12-point socket (almost-perfect fit). With two extensions plus some spray lithium grease, I cleaned up the body mount plates. Put on a face shield, used a flashlight and a pick and dug out the one rotten body bolt (behind right rear wheel). Now trying to figure out how to replace it. There's just enough left that trying to drill it out will be a pain.
Looks like a logical place on a wagon to get in there is through the fender well, which you can see also has the iron 'spreading' disease. There must be a 'bonus' water trap in there because this is the only rotten place on the entire car. The opposite side, same location looks perfect. When I do this side's bushings, I'll see if I can stuff a new upper bushing in there and lockwire it down with out a bolt so it does not fall out. Then at a later date, I'll pick up the whole body and do surgery on that side. I have a new rear brake line to route and it looks like a snap if I can get to the top of the chassis. Not for today.
I had to find the Prothane Malibu bushing kit in the Shed o' Many Things, and was amused that there were no instructions. Maybe got left out ten years ago. After some extended searching, I found a watermarked copy NOT on Prothane's website. If I put the Prothane instructions with Energy Suspension's instructions, I can figure out what I am doing. After 10 years in storage, they are a little 'greasy' with silicone oil.
Got out my new McMaster bolts (black oxide, like OEM) and cleaned and painted the upper half of them with anti-rust paint, then threaded in new bolts and the bottom half of the Prothane bushings down one side of the car, using a dab of anti-seize on the end threads.
Tomorrow or next weekend, I will lift the driver's side body and start swapping in the new bushings, then repeat for the passenger side.
