Just to follow up (becasue everyone likes a conclusion to a story)
I went out and got a few 8mm nuts and a 8mm gear wrench. I managed to use a few tips from people to get the last few 8mm nuts on the busbar..
8mm gear wrench with the nut inside with a dab of grease to hold the nut while a screwdriver pushed on for tension seemed to work just nicely.
Thanks for the follow up. It's always nice to know what works
Just wanted to say this thread was a huge help for my job of changing my glow plugs out on a 1990 Turbo Diesel Jetta I have. Screwdriver and grease saved the day. Thanks!
BTW, new member here, glad to have come across this site, I've had my car for close to 6 months now and am loving driving diesel.
if you wanna use individual wires between the glow plugs use a 14 or maybee even a 12 gauge wire. attach one of those round connectors to both ends of the wire so you can tighten it to the post of glow plug. So it look like something below. This is what I have done after I F'd my bus bar up. The VW dealership wanted $50 for a new one so this is what i did and i have had no problems at all.
