TBM it is many years if not decades since I last had a MGB GT, long before the availability of the interweb, and at the time I found Lindsay Porters GUIDE TO PURCHASE & DIY RESTORATION to be a worthwhile Haynes publication. Haynes number F303. ISBN 0 85429 303 5 I found it provides a real world idea relative to corrosion repairs and much else, thus providing an all round insight. Of course I suspect there will be more than enough detailed info on the web.. Good luck on finding a B that fits your needs..
