The exhaust system is a nightmare of patchwork. It exits the two manifolds with two pipes into the cat and exits the cat with a single pipe then into a "Y" pipe where it continues as a dual exhaust to the rear of the car into a 2 in/2 out muffler. In the middle something has been cut out and two section of exhaust welded in.

This is a low priority right now, but will be addressed at some point.

Today I replaced the very rusted original 42 year old battery tray with a new OEM one. Cleaned up some rust under the tray and treated it with POR15. Scuffed, cleaned and painted part of the passenger's side inner fender in prep for the new AC drier. I will paint under the battery tray once the POR15 has had plenty of time to cure.

Like FratBoy said in his thread, I too will look into an AGM battery to preclude future corrosion.

The other project wrapped up today was the installation of new carpets. Thankfully when everything was stripped out of the car I didn't find anything but a little surface rust on the driver's side under the factory sound deadening. Removed all the loose material, cleaned and coated again using POR15. I believe the very dry rotted and cracked door seals were probably a source of any leaks. Those too have been replaced.

I still need to restore the perished wind lace on the B pillar, but that is a project that can wait for another day.

Waiting to get the rear seats back from my upholsterer. He is replacing the cloth that hasn't survived well after 42 years as well as replacing the coconut fiber with foam. Fortunately the original MB Tex covers are in exceptional condition.

The interior cleaned up nicely. A few more small details like seatbelt covers and seat trim are all that is left.

Oh, and buy a set of Coco Mats to protect the new carpets.

Nice! The lacing of the old school steering wheel wrap needs more attention to detail imho. I used to be a stickler about that and seems I still am.

I don't disagree. The wrap was put on rather quickly and to make it look decent, IMHO, you need about twice as much of the lacing material. This will only be temporary until I fit a period correct original MB steering wheel.

What is that bolt next to the ashtray?

It's the socket for the locking lug nuts.

Considering ECS Tuning wants $745.00 for one of these new, I figured a little wire wheel cleaning and coated with ACF50 to stop further oxidation was a good alternative.

Well that's interesting. I have the same fan on my 82 turbo coupe. I've also cleaned mine up. I looked all over the interwebs and can't seem to figure out what color these were originally. Mine seemed to have a little bit of green or gold to it, but I can't really tell through the grime and corrosion.

I think I'm going to go with a satin-ish grey, just like the crank pulley. Is that ACF-50 colored?

It was either originally gray or just left a raw aluminum. The ACF-50 is a coating developed out of the aerospace industry to help keep aluminum and other metals from oxidizing. It is a clear coating that you spray on every year or two and the stuff is amazing.

I would have gone the extra mile to have mine sand blasted and powder coated, but I knew with the oxidation the metal would be very porous and would probably allow a lot of off-gassing and not a very nice finish. Maybe someday I will change out to a plastic fan, but then I have read that you need to buy the appropriate fan clutch. A smaller project for another time.
