I have just bought a 1966 B40, having previously owned one back in the early 1970s.
It doesn't have indicators as do the later models and I was thinking of fitting a set.
Can anyone post or point me to an image or two that shows how they were fitted to the later models, that might give me some ideas. Alternatively, if anyone has fitted them to an early model already, how you went about mounting them and where, would be appreciated. Trying not to drill holes in the original bike bits .

Afaict, the last B40's were built in 1970, but BSA didn't fit indicators as standard 'til '71. If you enter "1971 bsa b50" into your preferred internet search engine, it should return images showing standard indicators fitment. Not much different from the contemporary twins.
First of all you really will need to upgrade the electrics as there is a better than average chance it is 6V. Next there are laws regarding separation of blinkers front & back, min heights, maximum heights etc etc etc so check with your local authority before you do anything. Using those short "harley / bobber " style ones that fit directly over or replace the headlamp mounting bolts is in fact illegal in a lot of places. There was a reason why BSA fitted those Lucas blinkers on those silly long stems and it was not to make them look sexy.
There are some nice neat LED indicators available. I would personally steer clear of the Lucas units. The bodies are chromed plastic and not very securely fixed to the stems, hence the lenses often pointing to the road

I'm sure this is correct, however from May 2018 in the UK, vehicles older than 40 years will become exempt from the annual MOT, which presumably means any rules relating to fitting indicators wont apply but I'm happy to be corrected if this is wrong.
As I'm currently restoring a 1972 Norton Commando, I have been looking at various potential replacement indicators. I probably won't use the original Lucas version and the led types seem to be viable, so I will be following this thread with interest.

From personal first-hand experience, in GB, the only conceivable "local authority" that could have any interest whatsoever in indicators mounted on your bike is the police. The possibility that you'll meet even a 21st century traffic cop who even knows 1971 Construction & Use regs. exist, never mind how they might be applied to a '66 bike ... well, if you do, don't bother buying any lottery tickets for a while ...

Nothing to do with most bodies, usually that's the stems coming loose at the mounting; the only bodies that can rotate on the stems are very early ones - that had a 7/16"UNC thread (99.9% now wrecked) and poor-quality pattern ones - that have a round mounting hole in the body. Certainly the vast majority of 'original Lucas' bodies have an oval mounting hole, that fits over a stem with two flats on the 3/8"UNF thread; 'course, these can be rounded by some dipstick forcing the body around the stem ...
