quote:Notice that this zf does not have a fill plug on top?
My dash 1 has the filler on the left side. Car serial #1490.
As I recall, the filler is made up of an AN 90* fitting and the B nut. The dipstick was made up from a thick flat disk with a hole drilled in its center and a really heavy cotter pin. The cotter pin was inserted into the hole in the disk and silver soldered in place. One "leg" of the cotter pin was cut off, and the other "leg" was stamped with two "lines" to indicate min and max fluid levels. This was the ZF dipstick that came with the car as delivered new.
