I've got a quick question re: a Hinson basket:

Do these require any additional parts when installing?  Or, does the basket just replace the stock basket?

I ask because I have one I took out of a spare motor I have and will be putting it in my (now) running motor this weekend.  The stack of pieces I have with it from pulling out of the other motor seems to have a spare washer with it.  When looking at the exploded view in the manual (page 3-49 of the 88-92 manual) I've got two of the washers that go between the basket and the "Clutch Sleeve Hub"  It could just be a spare from another stock clutch I sold however, the weird thing is that the back of the "Clutch sleeve Hub" where the washer touches has a worn in mark of a 4 sided semi-star shaped thing.  I can't find a washer with these parts that looks like that, though and it's obviously not shown in the exploded view.
