transmission compatibility? 1979 300sd to 1980 300d

hi, i have the excellent guide on how to replace transmission, and am about to try this with my dad. he has the transmission out of the parts car, a 1979 300sd, and the torque converter wouldn't come with it (broken timing chain so no turning over). before we take out the badly slipping transmission from my 1980 300d, we're trying to determine compatibility issues. any known problems?? any help much appreciated, thank you! -noah

Boom, Coolant vapor all over inside the cockpit

I recently got an 85 300sd with an engine that only has 92000 on it. The car drove great till I heated it up on a 30 min trip home from work during the hot part of day. I was just about home when I turned on the A/C, ahh it was nice and cold, but at a stop light the engine started to make some strange vibration and a few minutes later coolant vapor burst into the cockpit (not very nice while you are driving). I got the windows down and pulled over and the vapor slowed down, but the engine temp started to get hot.

someone put 134a in my '84 SD. Can I go back??

I was getting things together to get started, new drier, new expansion valve, refrigerant and 'oil..' I was going to draw it down today-- and get to work this afternoon.. My freeze-12 (drop in "Freon" replacement) arrived a couple days ago.. Here's my problem.. Uncapped the lines, to find one has been "retrofitted" to 134a. My questions are: 1) can I just wrench that off?? It looks like it's just a screw on fitting. 2) the BG refrigerant oil is compatible with both 134 AND R-12 "freon" so I'm thinking that isn't an issue.. 3) do I need to replace the receiver drier and expansion valve, and pretty much, go on with my life??

Cams to be used in 1979 300D

I currently own a 1979 300D which has a "worn and scorn" cam. The rocker arms near the front are worn also. This engine has the "00" cam installed. I was given a newer cam and rockers by a friends dad. It is the "05" cam which is the newer "hardened" cam with higher lift. Can this cam and rockers be used in my 300D with engine: 617.912 1207. Too the newer cam has the MB Emblem stamped in it along with the 617 05 between the number 3 and 4 cam lobes. Help someone......Kent?
