1) Should I have him pull the fuel pump for me ? I think he quoted me $200 (or was it $300?). Seems like good insurance, especially since I am running WVO.

2) My winshield has a speckled look which makes visibility less than optimal in some light conditions. I think this car's is better than mine for some reason (though I need to make certain). He quoted me $85 plus the cost of someone to remove it. What do you think? Way cheaper than a new one, but do I even want a new one -I have heard they are not so long lasting these days?

3) I am trying to pull the steering column on this junkyard beast to access the turn signal shaft - since mine will not click back. I couldn't get it and the guy told me I stripped the hex socket of the steering column (which is not very deep) to the point of not being able to remove it. He is going to try and pull it for me by chiseling it down or something - maybe just by tearing off the steering wheel. My question is - is it worth the effort? If I couldn't pull out the junk yard steering wheel without stripping it will I strip mine as well while trying to replace it? Plus, there's the question of whether this $40 old replacement turn shaft will work at all... Apparently, unlike the W123, you have to pull the steering wheel on the W126 to access the turn signal - I saw no other way. Has anyone ever pulled out the steering wheel and how can you do it - does it need a special hex tool?

1. Sound expensive for a fuel pump. You mean injection pump?

2. I had a new windshield installed in my 83 300SD for around $150. Why buy used?

3. It's a 10mm allen bolt. Need to remove the steering wheel on both W123 and W126 to access combination switch.

Actually, you don't have to remove the steering wheel on the W123. Take the boot off the switch, then remove the two screws holding the switch in, two wires for the horn, and it comes right out by fishing the wire harness through the steering column.

As for the "turn signal shaft", are you talking about the steering shaft? If I am not mistaken, there is simply a steel block welded to the shaft that the switch contacts to trip it and return to center. Unless this block fell off, any non-centering problems are likely in the switch itself.

As for the windshield, you may want to look into new instead of used. Some new windshields are actually very reasonable in cost. Here is one site you can check that will give you an immediate quote:

Take yourself a two x four about four feet long will do. The idea here, as many here have suggested, you do not want to rely on the steering lock to hold the steering wheel in place while you are trying to break the lock nut free.
You may not care about the junk car, That's cool. But you will need the wood for your own car. The trick here is to place the wood through the steering wheel letting it come into contact with the floor. As you wrench on the lock nut in the steering wheel, the steering wheel will turn a little and rest against the wood. Now you can leverage the force against the lock nut without the steering wheel turning any farther.

Be sure to use a very high quality 10mm hex socket. These seem to fit much more snug into the lock nut.
Also if you feel up to it remove another lock nut from another car to use as a spare at home. Should you chew up your own lock nut a little.
