Update:

I got the new boots from Napa. They were MUCH beefier than the dorman ones. They appear downright OEM(ish).

I got both the outer and inner since the quality seemed better, I am going to replace both, but save my inner as a spare.

I have one new question though, the NAPA inner boot (separate part number) contains a larger bag of green grease. Seems less "greasy" in the bag than the black smaller bag for the outer, but maybe I am wrong. Its a larger area to fill with grease though.

Can I just use any old "CV Grease" in the inner and not worry about it?

EDIT:

Reading some "googles" looks like green might be better....Hopefully I dont booger it up.
