  1. 450SL on eBay

    R/C107 SL/SLC Class
    There is a 450SL on eBay claiming to be a 1977, but based on what is under the hood and the lights and bumper it must be a 1973. Is there somewhere to run the VIN to tell for sure? 107044-12-012500 :confused: This is the bright yellow 450SL with euro lights and bumper.
  2. Cruise Control Module

    R/C107 SL/SLC Class
    Has anyone had any dealings with ProgRama or General Development Laboratories? The GDL site has lots of good information on the Cruise Control system, and wants $385 to rebuild the Module, lots of caveats about original condition and not tampered with previously. ProgRama will sell a...
  3. OT American language

    R/C107 SL/SLC Class
    And if you live in Maine you learn that the hicks do not know the word wasn't exists. As in "I weren't there." We all have our crosses to bear.:(
  4. Haynes Location Code

    R/C107 SL/SLC Class
    I hope these two photos might be of use to someone else who is using the Haynes Book to work on their 450SL. These refer to the numbers on page 172 "Key to the 1976 wiring diagram". I am still looking for some of the other parts and if I find them I will add to the photos. I found that by...
  5. Strange Idle

    R/C107 SL/SLC Class
    Well after several hours of troubleshooting and testing, I replaced the brand new Injectors installed two years ago for a set of used tested injectors and the problem has finally cleared up. She starts, runs and idles like a dream now. Does anyone know where to find the Hot Start Solenoid?
  6. 1975 450SL For Sale

    R/C107 SL/SLC Class 'For Sale/Trade/Buy' Forum
    For Sale is my 1975 Black 450SL. I am asking $3000.00 I would like to free up some space in the garage, and I really do not need 6 insured and registered vehicles for just my wife and I. So, the 1975 has to go. I would like to to get $3000.00 for it to off set what I have in it. It has new...

  8. Fuel Gauge Sending Unit

    R/C107 SL/SLC Class
    On Labor Day I decided to investigate why the gas gauge on my 1975 450SL always read 1/4 of a tank. Attached is what I did to fix the sending unit.
  9. My new European 1972 350SLC

    R/C107 SL/SLC Class
    Door Locks Did you ever get an answer to the door lock question? If it is like newer model 107-044 you lock the drivers door with the key and it locks the passenger door, trunk, and gas cap cover. If it does not there is a vacuum leak as all the devices work off vacuum reservoir under the...
  10. Moody SL ... I can sense when she is feeling good ...

    R/C107 SL/SLC Class
    Yep mine all have good days and bad days. But I notice that the 76 seems to run/ride the best with the wife behind the wheel.:D
  11. Thinking of buying a 450SL

    R/C107 SL/SLC Class
    OMG - Buying a car that is nearly forty years old is a crap shoot at best. I have purchased two 450SL cars as "parts" cars and am driving both of them. One, the '75, cost $1500.00 and needs a paint job, but what blast to drive, it actually gets rubber! The other, a '76 bright red, looks great...
  12. Fuel Screen Replacement

    R/C107 SL/SLC Class
    The screen insert has a rubber O ring that seals against the bottom of the tank so no need for Teflon tape on the insert. I used gas rated pipe thread seal on the hose to pipe thread adapter that fits into the insert. You may have to take the tank loose in order to get the insert out and back...

  14. Strange Idle

    R/C107 SL/SLC Class
    My 450SL has a very strange idling problem. When it first starts it idles okay until the AAV closes, then it will idle at 700 RPM for 30 seconds and drop to below 500 RPM for 7 or 8 seconds then return to 700 RPM and it repeats. It also has a very bad hesitation and surges when running at...
  15. Directional Lights

    R/C107 SL/SLC Class
    All three of my 450SLs have the same problem; the directional lights do not turn off unless the turn is very tight. So more often than not I drive for miles with my directional lights still on. In an effort to correct this I installed a small device I found on ebay which can be adjusted as too...
