Non starting engine - Changed my ground strap. Car started first time. Hooray. Then later wouldn't start again. Looks like I'll have to start again on that.

Fusebox - removed/cleaned fuse box and replaced all fuses. Mainbeams started working again but horn still doesn't. When I pulled the horn I could hear a clicking in the front behind the battery. Removed the battery and found a very rusty sorry looking relay. This might not be the problem but it looks like it could do with replacing. Anyone know what type of relay it is?

Sunroof - found why the one side won't open but it wasn't a snapped cable. The whole metal hinged part thats attached to runner and roof had sheared off and fallen back into the roof. There's still part of it attached to the runner and cable. I presume I need replacement parts but from what I've read on they don't make them anymore.

Engine temp sensor - It doesn't work and I think I've found the reason. I think there's no wire attached to the sensor. I found what looks like the sensor, a brass looking bolt with VDO written on it just down a bit and to the right of the fanbelt. Is this the correct place for the sensor on a 68? All I've got to judge it against is the project in 101 but that isn't for my year of car.
