Thanks everyone !
It's a Britax factory fit sunroof so hoping it's going to be better than an aftermarket job, but will keep and eye. Worst case I'll remove it and get a panel welded over, or splash out for a Tudor/Webasto. She's been garaged for the last 6 years, but she'll have to live out in the open with me. I will probably get a cover, but it'll be a faff having to remove every morning at 6.45am, and won't be able to dry her off if it's raining. Maybe a smaller cockpit style one will do.
Will keep an eye on the suspension - I live on a 20mph road with numerous speedhumps, so will see how I get on first before I look at lowering. Proably refurb the armstrongs and go for the SSL adjustable valves - really impressed with them on the Mog and only about £90.
It has an electronic ignition but I think it's an Accuspark - not very impressed with the reliability of them (had two fail on the Mog) so may splash out on another H&H kit - given me no issues since I fitted to the Mog. I think the carbs were refurbed when the new tank was fitted, but again will have a look. I really want to squeeze as much mpg out of her as possible.
First plans will be tyres (Tread good but not sure of age), suspension and brakes.
