Completed the "final" (I hope) painting of the truck. Now on to interior and electrical efforts.
I had a strange surprise, I had an accumulation of fluid under the seats that was leaking through the drain hole onto the transmission output shaft/u-joint. Apparently the '90's vintage Chevy seats I installed have a fluid reservoir associated with the passenger air bag system I did not realize. When I removed a bunch of the extra junk under the seat prior to install I opened that fluid reservoir to drain onto the floor. At first I thought I had a transmission leak (puddle on the floor under the truck) but finally determined it was the seat leaking, totally unexpected.
