Time flies/flys. I posted last about a year ago. This is what I've done so far trying to get the car roadworthy.

Replaced rear wheel cylinders
Replaced front calipers and pads
Replaced master cylinder
Added new style glow plugs
Found two nice front signal housings in Canada for $65 total
Right rear tail light lens from Germany for $150 total
Left rear tail light lens from Istanbul for $50 total
New battery

My friend helped me bleed the front calipers the other day and after a test drive we believe the booster is bad due to a very hard pedal. Does anyone know if they can be rebuilt? Can it be removed without taking off the master brake lines? I can't find hide nor hair of one anywhere on the internet. The engine fires right up and it is fun to drive it around the neighborhood. We felt like diplomats with the Mercedes symbol on the hood shining in the sun. It ain't pretty, but it does turn some heads. I will be adding a collector's plate soon. Thanks for any help.
