Re: 72 K20 been parked for 31 years!!

Also wanted to share some of the additional O rings I added along the way to help make t case as leak proof as possible. Also I used blue locktite on all threads so hopefully fasteners wont have seepage either.

R22 o ring on the center shaft between the washer and shaft.
R14 o ring on speedo drive shaft nut
RTV under washer and R11 on top off front output yoke nut.
R05's under detent spring plugs (top of case)
