This job really sucked. I am the one that wrote the article for crownvic.net decades ago, and on the 2002 and below, the frame crossmember makes this job a living nightmare to do. 2003+ frame redesign with the rack and pinion steering are much better. I dont care how good of a mechanic, or how many tricks or hack you have up your sleeve, the only way to get to the top two bolts is to unbolt the AC compressor and move it aside. It does not need to be disconnected. The feed a whole host of different extensions and wobblys back to the bolts.
Took 6PM to 10:30PM. AC compressor bolts hardly came out. They were nearly seized into the aluminum compressor body.
Needless to say the top bolt will never ever be going back in.
