I realise this post has been out there for a while but pretty topical seeing as I've spent so long under my disco the last 2 weekends. I spent ages trying to get the top nut off with every combination of ratchet extensions and UJs. I still ended up rounding it off, so had to leave it there. I bought the solenoid kit off ebay for £8 so had to put it on in situ. Its a bugger to get to because of the confined space but its possible. The only thing I would do different is to reuse the nuts that were on the solenoid contacts. The original ones were a bit deeper than the new ones and on the far side bolt it was really difficult to get a spanner in and make it tight. I tried to take it off again but I just couldn't get the leverage on it. It will probably loosen over time, I just hope its not in the middle of nowhere.
Well that was my first post over with. Hope my experience will help someone!
