300sd engine swap...parts replacement recommendations?

I am changing the engine in my 82 300sd (due to low compression on one of
the cylinders/poor starting in ontario winters). I want to be sure I do
everything that should be done while the engine is out of the car.
I have ordered the front main seal and a bunch of other stuff.........but
I see no mention or guides available for the rear main seal. I'm not sure
if the engine being transplanted should have a new rear main seal, or if it is an easy job....... or not.

Anyone with any experience or info on this?

1977 300D coolant leak

Last year my parents bought me a 1977 240d with a 300d engine. I love the car because of its old style and drove it for about 4 months before pools of coolant started to appear under my car. I am wanting to fix my car now that my dad recently passed away and i need to know if anyone could help me by finding out what the cause is. I have had people tell me its a freeze plug behind the engine. All can tell is that its leaking between the engine and transmission. if anyone could answer this for me i would appreciate it and i would know that i must purchase a freeze plug.

84 300SD OIL HOSES/LINES

Are the couple of hoses at drivers side of what I think is an oil cooler are those the oil lines? These hoses are like a hydraulic line, alterante between rubber and preformed special metal fittings and shaped metal lines. They appear to be a pre determined length and appear to go back near the trans. If so are they easily replaced? Cost and availability of the lines and do you have a how to guide? I recently used your ignition switch guide and replacement parts. Thank you it was quite helpful. One other question is the oil pan and gasket available through you?
