starting problem

I have a 76 300D that I am having a strange problem with. Usually the car will start without any problem two or three times, and then it will appear that the battery is too weak to even make the car turn over, although the headlights and other electronics still seem to be at full power. I have had the alternater tested and it seems to be working fine. I took the battery back to Wal-Mart and their machine (as well as AutoZones) found the battery to be good.

1975 230 parts help

I bought a decent, very original 230 sedan a couple weeks ago. Overall the car is in pretty good cosmetic condition but the engine needs help. The compression is below the minimum at around 100 to 115 pounds. It does run but it's pretty weak. I've searched online but haven't been able to locate a source for parts to rebuild the lower half. Pistons, rings, bearings seem to be a rare commodity for this engine. Is there a source I've missed or are the parts just difficult to come by?

76 240d need to shut off under hood.

I recently purchased a 1976 240D and it does not shut off. I have read about the vacuum for the 77 and on with the 123 bodys. but is this different for the 74-76 115 240d's? Thanks in advance for any help. Thomas
