Mercedes lug bolt restoration

I have recently purchased a set of 15×7 AMG ‘Penta’ wheels for my 1977 450SLC. These wheels did not come with lug bolts, but I had a set from when I had the replica Fuchs alloys on the car. The other day I got those bolts out to check them for when I install the wheels on the car.

The bolts were in pretty good condition overall, but suffering from surface rust, particularly on the heads. That wouldn’t look very good with the new nice wheels. Instead of buying new bolts, I decided to see if I could perform some […]

W107 Foglight lens replacement

Earlier this year I managed to smash a foglight lens on a MBCNSW drive to Berry. I drove over a large stick on the road that flicked up and smashed the lens. I saw the stick, but there wasn’t really a way of avoiding it without risking an accident. The low slung floglights on the 107 model look cool, but they are always at risk of road debris. I’m pretty lucky that after 18 years of ownership, this is the first time I’ve smashed a W107 foglight lens.

In the short term, I removed the broken lens so I didn’t […]

C107 rear windscreen installation

Back in May, I had the rear windscreen removed on my 450SLC. The idea was to replace the old windscreen that was delaminated with a good used unit I had purchased from the MB Spares clearance sale. I had the rust under the screen fixed in 2006, so I assumed it would be a straight swap. Sadly, during the C107 rear windscreen installation, no sealant was used. over the years since, water had seeped between the seal and the body creating rust.

Obviously I wasn’t going to put the new window in with the rust around the aperture, so I […]

Choosing tyres for my 15×7 AMG Penta wheels

My new 15″ AMG Penta wheels did not come with tyres. Choosing a set turned out to be a lot more complicated than I thought.

The big downside of the 15s over the 16s is the tyre availability. The table below outlines possible sizes I could have considered. They are all compared to the overall circumference of the original wheel/tyre combination.

Tyre SizeRevs per KMDifference 205/70 R14496Standard 205/65 R15492+0.8% 205/60 R15508- 2.4% 215/65 R15482+ 2.8% 215/60 R15498- 0.4% 225/60 R15489+ 1.2% 225/55 R15506- 2.4% 235/55 R15498- 0.4%

The easiest and most obvious choice would have been one of the 205 […]

15″ AMG ‘Penta’ wheels for my 450SLC

I’ve been on the lookout for a different set of wheels for my 450SLC. It is currently running a set of W126 second generation alloy wheels. I like these wheels, but they are not quite right for the 450SLC. My 560SEL uses these same wheels, but they are in need of refinishing. Instead of having some of my spare W126 wheels refinished, I thought I would get a different set of wheels for the 450SLC and use the refinished W126 wheels on the 560SEL.

I thought of a few options for the SLC.

Standard 14″ Steel wheels with colour matched […]

450SLC rear windscreen screen rust update

A couple of weeks ago I discovered rust around the rear windscreen in my 450SLC. At the time, I was having the 450SLC rear windscreen changed for a unit in better condition than mine. The rear screen seal was replaced back in 2006, but no sealant was used. Even though the car has been garaged the whole time, water had gotten stuck between the seal and the metal. While the cars were originally built without additional sealer, it is generally a good idea to use it. It stops the water getting stuck behind the seal like it did on my […]

450SLC Rear screen rust

A couple of years ago, MB Spares & Service closed their spare parts division to focus on their restoration and servicing business. At that time, I was able to buy a very nice rear screen for a C107 SLC. The car that it came out of was very rusty, but surprisingly not around the rear screen. My screen is quite delaminated from previous rust around the screen area. As you can see from the picture below, the new screen is really good.

After having that screen sitting in the garage for the last couple of years, I figured it […]

450SLC Passengers floor surface rust

Back in March, I discovered how wet the passengers floor was in my 450SLC. Over the time water was getting on the floor, it had started some surface rust. It appears that at least some of it was coming from the A/C drains. I still need to test a hose on the windscreen and cowl drains to make sure water is not getting in from there too.

Obviously the most important thing is to fix the source of the water. I also felt it was important to fix the surface rust on the floor. It still wasn’t too bad, so […]

450SLC wet feet

I’ve had a problem with wet feet in my 450SLC for years. Generally this manifests itself with water dripping onto both the drivers and passengers feet when the A/C is running. This is particularly prevalent when going around a corner. I had always assumed that this was caused by blocked A/C drains. I tried to clean them a couple of years back but the problem never went away.

A couple of weeks ago I took the car on an extended drive and had a lot of water covering my feet, but especially in the passengers side. I figured it was […]

Rear brake fluid leak on my 450SLC

I’ve used my 450SLC on a few spirited drives lately. With the new injectors its been running really nicely. However, on the way back from the most recent night drive, the pedal became really spongey on the way home. Luckily it was late at night with few cars on the road so I was able to drive it home gently.

The next day I had a quick look under the car. I noticed there was a lot of brake fluid on the drives side rear tyre. Looks like I had a rear brake fluid leak on my 450SLC.

I […]
