Looks like it's closing time in Georgia (they're Eastern time over at Rusty's operation I guess). Was trying to call them and ask which glow plug to order. My engine number does not match any of the provided numbers on their glow plug page.
I guess my engine came out of an '82 240D. Maybe I'll type in '82 for the year and see what comes up. Didn't think the engine number would be any different. The number on my engine is: 616 912 10 268124 Brian 83 240D
