The following sites carry information on a variety of topics:

So good it deserves a line of its own right at the top - a set of 'How to' videos from John Twist and University Motors

I've had to delete the links to the MGOC articles on things like axle clonk repair etc. as you have to be a member to get access to them now. But even then it isn't easy finding them - you have to go to Members Area, Technical Archive, enter search terms and select 'Within Enjoying MG only'. Looks easy written there, but I had to have several goes to get there the first time.

NOTE: Check the legality of these in the UK following the change in UK law from 18th September 2006, although it seems that systems with an older BS approval marking will remain legal until May 2008. Other than that it is legal to have an unrestrained child (or two) in the back of a GT, but illegal to have them restrained with an unapproved system.

	Solent Wheels, who apparently make a good job of refurbing V8 wheels where the chrome is peeling. They powder-coat the whole wheel silver, then top-coat the alloy with satin black, and polish the areas round the cut-outs, all for £50. They do not split the centre from the rim in the process as re-riveting is an extremely safety-critical process.		My local wire-wheel rebuilder - Phillips & Son, Unit 3, Seven Stars Road, Oldbury, West Midlands, 0121 544 9060, just a couple of minutes from J2 of the M5. The map (click the globe) has the green arrow close to where they actually are between the canal bridge and the A457, even though that is shown as Park Lane and not Seven Stars Road.
	Central Wheel Components. They can make stainless spokes to fit MGB wheels for you to fit but do not work on the wheels themselves, only motorbike wheels. Highly polished they are close to chrome, but are said to resist breakage better.		Weights of many wheels, probably all after-market.
	British Wire Wheel - based in the USA despite the name. Sell both Dunlop and Dayton so a useful price comparison.

	Clive Wheatley. Clive specialises in V8s both factory and conversions, but can also supply parts and services for all MGBs.

Leacy as was, quite local to me in Brum and a huge stock as well as a good online store with many items photographed.

Solved a long-standing wheel wobble problem on the V8 with their highly specialised 'Road Force Measurement' machine which uses precision stud hole adapters rather than the centre hole.

Good rates (only 5% increase for 2011 whereas the AA indicates many providers are increasing rates by 20% or more) for both classic and modern, efficient courteous service, a months notice of renewal rate to give you plenty of time to look around, and finally a sensible approach to agreed value revaluations. In this last aspect I had had the roadster with another broker for very many years, and they always insisted on a 'professional' valuation every couple of years. This wasn't too bad when I could get it done locally by a classic repairer for a bung to his tea-club, but he eventually closed down. The broker wouldn't accept my photos and valuation, but they would accept a valuation from another insurance company if I sent my photos to them - ridiculous! By contrast for cars like the MGB Footman James will accept the owners photos and valuation, and what's more have just extended the interval from 2 years to 4.
