Does it have to be Hazet, and where are you located? I have the two wrenches, the ones that hold the jam nut and adjuster. Parked my W123 around seven months ago and thinking I may sell them. Bought them here a few years back and they worked fine. I also have some (maybe 8-10) new in box Bosch glow plugs (pencil type) for a 617.952 also.
I bought them (GPs) from an online seller that was closing out their inventory when I was looking for five.
