I made a dip box to dip paint upper A-Arms. I got the measurements down to use about 2 1/2 quarts of paint but the shafts, mounting bolts and bushings need to be off. If I made a dip box big enough to include those items the "box" turns into a 2 gallon monster. I'll brush paint them after they are installed. The two arms with riveted ball joints are NOS for a friend's Shelby, two of the other four came off my "K" car and are for one of my other Mustangs and the other two "may" wind up in another Shelby. This is my second use of the dip box, the first attempt (successful I might add) were to prepare arms for my "K" car that came off that first Shelby.
Yes, I'm in SF Bay Area, see the lemon tree in background in the second picture.
