Nicely done. That type of detail work was always my favorite aspect of a restoration. I know many of the finishes can no longer be duplicated exactly because of environmental concerns.

Here is the OEM BOSCH for $900

I have the pads and yellow BOSCH sticker so I don’t get -1 from Concourse Judges!

It’s such a pleasure to work with competent vendors; they had 7-day turnaround, reasonable and advised on correct finish.

They do Custom Chrome and LA vintage Porsche guys use them.

If the Benz purists are like Shelby Mustang purists, nothing beats the assembly line part. And they can tell the difference between the assembly line piece and an over the counter service part in an instance.

The Benz purists are a whole new level of authenticity.

There is the added level of NOS parts still wrapped in wax paper and packed in wood shavings.

Daimler-Benz archives / parts repository is awe inspiring.

Rolled up sleeves and got this done: frames were rusted, incorrect SAE sheet-metal screws, mis-alighed beams.

-Disassembled rusted frames, tabs, and screws
-Sent out frames to be zinc plated

-8 correct M4 zinc coated screws with camphered ends (not $17/ea. from M-B!)
-8 5/32 neoprene washers.

-WD-40 in threaded holes; were rough from wrong screws; oxidation.
-Used new SS 4mm screw with anti-seize slowly on each thread.

-Blue taped headlight buckets, grill, chrome; test fit, frames have razor sharp edges.
-R+R all parts; slowly and patiently

-Installed New HELLA H4 flat glass beams
-Aimed beam pitch V/H; fine adjust.

Everything came together flawlessly; pleasure to have spotless, clean parts, correct fasteners with positive engagement.

Bonus:

Ordered PB Swiss Screw-driver set prior; right instrument, precise rotary torque; zero cam-out; parallel machined tips.
