Harvard,
Yep ... that Ingalls part appears, shapewise, to be for accomplishing the same thing as the part that my RV shop installed - except that the part my mechanic installed was not nearly as long/tall as the Ingalls part. My part was just a very thick beveled washer type part, perhaps only 3/8" - 1/2" on the thick edge of the beveled washer.
Sounds like they installed a fixed non adjustable one piece collar, the Ingalls 594 are two pieces that rotate for various (infinitely adjustable from -2.0 to +2.0 caster and camber) settings. The neutral caster position is about +3.0 so you add +2.0 to have a total of + 5.0 degrees of caster.
Did you happen to get an alignment report?
