Andy at AJC Conversions has done our carpet lining and insulation with some electrics(lights and sockets) last year then this week had our windows fitted which is not the normal way round of doing it but it was not a problem for him and what a great job they do. They have a great eye for detail which is good because im a bit of a perfectionist I: . As he is a T5 owner he knows what works best in these buses. Look on his web site www.ajcconversions.co.uk or search for some threads on the forum.T:I'm surprised no one has mentioned AJC conversions yet, but he is your way and gets good recommendations on here.
Of course you could use us, but if you dont want to travel far then I suggest a look at Andys work.
