For whatever reason, everything is more difficult on the smaller engine: more tools, more time, more work, more grime... The upper bolts are 1/2"; the lower nuts are 11/16" (and their studs came out for me); the P/S box fitting is 5/8"; the 5 compressor bolts are 10mm; the air tube clamps are 8mm; and the tensioner takes a 3/8" square. I used a 3' extension to go thru the wheelwell to the bracket's lower nuts. Apparently, some early 4.9Ls use shorter studs that may not be long enough to reach through the later Saginaw bracket. I'm going to try to research that issue...

I guess I need to change that side cover gasket sometime...
