Because my Sweet Tomato is in good driving condition, I don't want to tear into it any more than I have to. It's a 74 450SL built Oct 73. The gauge cluster isn't seated properly in the dash and slides out about 3/8" while I'm driving. Before pulling the steering wheel and the cluster, I need to know is the Oil Pressure gauge is electric or mechanical?
Not sure if something is interfering with properly seating the cluster under the dash lip or if it's just the lip itself.

Don't know about the oil pressure gauge on yours but there is a rubber grommet all around the cluster. Perhaps it has come loose.Also, If you remove the driver side bolster you s/be able to see what's happening behind the cluster.

Mechanical. It's a very small line. You have to remove the wheel with a 10mm allen wrench. Need an allen socket and breaker bar and piece of pipe or something to hold the wheel. May not be that tight if someone has had it off. The cluster should come out with a couple of small wire hooks. Mine I can just pullout with my fingers but in never moves or slides out while driving. The only thing that is a little awkward is the speedometer cable it is kind of a tight fit. Not much play in the cable. Oil pressure is easy
Also there should be a piece of plastic the length of the panel underneath it. Maybe it's upside down or not seated properly.

On all of my old mercedes the instrument clusters are pushed out a little. I think the dash shrinks over time and squeezes it out. I've never needed hooks to remove, just pulls out with fingers. It does have a rubber gasket that may be disintegrated on yours. Part number is 114 542 02 80 but I don't know if it is still available....

Its basically a giant rubber band with ribbs in it. Just kind of grips the opening

Gosh! Maybe I am just fortunate mine was not exposed to harsh conditions. I had no idea the dash or opening around the cluster could shrink that much!

I give mine a good shove back into the opening every month or two. It slowly works out but not very noticeable. I'm sure new rubber would fix this but It doesn't really bother me

Thanks, Guys. I'll probably pull the wheel and see if there's a way to get the cluster seated. The car spent many years in California, so the "rubber band" may be dried out or disintegrated. Thanks again.

I don't remember seeing a rubber band. I have taken it out several times. I either just didn't notice or maybe that is why it fits so well! Now I am going to have to pull it out and look.
