Yahoo ~~ Got it done. Found that I had #21 on your diagram (attached here again) upsidedown. When I disassembled the whole thing it flipped and I just assumed (dumb....) that it went that way. But thanks a million for the diagram. Got it rightsideup and things came together pretty well (see attached completed pic). I did also find that there was no #22 on either side. So I took one of my former/worn seals and gently cut it down the middle and made what were essentially two of the #22's.
Thanks millions y'all !!!
