Alternator mounting

Aloha
I have a 1990 YJ with the 4.2 L engine and no air conditioning.
As part of some other work, I removed the alternator and its mounting
assembly including the idler pulley assembly. The problem is that in the
process of doing this a sort of c shaped larger spacer/stiffener and a
small washer sized spacer fell to the ground. Does anyone have a link to
an assembly drawing of the alternator/idler pulley mounting?

It was stupid not to be more careful, but it wasn't the first time I
screwed up and I am sure it wont be the last either.
Thanks in advance

Aloha
