I got mine done,took a while …but there was no body filler

Well this topic has taken an intruiging turn. I had a look at the somerford site, and they list quite a variety of fixes. All the parts books we usually use here show 13H217 which is the plastic fix mentioned above, but it seems earlier cars do not use this. Here is a picture of a metal fix from my own 850 (UK style boot) and a 13H217 plastic fix. There is no way that the plastic fix will fit in the holes of my boot lid. But alas, neither Doug or I can find any mention of a metal fix between us even though the drawing shows a smaller hole prior to 1965. Those somerford mini parts may be genuine parts, but I have usually found that part numbers beginning with G are often unipart listings and not the original BMC parts.

Actually, launched in UK in 1969. The branding was always written in all capitals UNIPART, but company documentation shows Unipart, UNIPART, Uniparts, so it seems there are some variations depending on context. Unipart operations began in Australia in 1977. I apologise deeply if anyone was confused by my editorial error. regards, Tony

Well, if I were to choose between Wikipedia, which is where your quote apparently comes from, and a company document, I would choose the company document any day. Picture below snipped from company brochure "The World of British Leyland" Annual Report 1972 published by British Leyland.
