1984 300D still very slow

I've followed along numerous posts on this subject and followed instructions where I could, but my car is still a DOG.

I have performed all of these fixes yet not realized much difference:
-Cleaned banjo bolt
-Replaced air/fuel filters (many times)
-StarBrite anti-fungus fuel additive
-Replaced some vacuum connectors (not the 3-ways, just the small pieces - I'm poor, but working on it)
-Replaced brake booster vacuum line - it had 2 broken nipples.
-Replaced vacuum switch levers (the two plastic things on top of the valve cover - whatever they're called)

240D Standard Transmission Shifting Problem

Have a nice 1982 240D four-speed, standard sransmission (floor shifter) with about 140K miles on it. Recently experienced big problem with shifting from one gear to another. Thought it was a bad shifter and secured a replacement assembly unit which has been installed this past week. Have replaced all external bushings (except for white plastic bushing inside actual shifter unit)and everything appears to be tight...not loose. Can replace internal shifter box bushing but I don't think this is the problem.

300D dash lights fail after radio install

My old Becker radio in the 300d gave up, so I replaced it with something new. Everything seems fine except now it seems I have lost dash lights? Any advice would be appreciated.

Was having hard starts in the cold last week, the glow plug light went out. Ordered the clean=out tool and 5 new glow plugs. Job went smoothly with your instructions. Starts great again, Thanks!
