Probably one of my most technical questions ever , Are bolts or screws used to mount the washer resevoir? Finally got my hands a decent one and can't tell if their are real threads in the holes on the body or not with the fresh paint.
I hope the picture works. Mine is attached by Phillips sheet metal screws with captive washers. I purchased my car from the original owners in '89 and have every reason to believe thse are original mounting screws. I replaced the original bottle many years ago when the whole top caved in while putting cap back on.
The 69 part tucks up under the fender next to the battery, with a neck that sticks out. 70 mounts on the fender well, in front of the battery. The 69 is a better solution I think, hidden out of the way.
