I would probably try a Salvage yard that specializes in Mercedes first. Any large city (>200k) is bound to have at least one.
5) Power antenna stuck up...motor not working.
Most likely it's the mast. When you turn the car off, can you hear the power antenna motor? Very easy fix either way. The mast is about $15-$20, the motor is about $40. Look on eBay, there's a guy from San Diego selling them all the time. Mine was stuck midway, got a new mast, now it works great.
7) (This one might be silly)...The cruise control doesn't seem to engage at all...were they reliable in 1975 and is it normal for them to be non-functional? This is just for information...I would probably not spend money on this right now.
