You are right. There is no spacer on LHD cars. Unless somebody tells me 
that we are considering a LHD car, I assume RHD. You will no doubt do 
the opposite

Just to be sure and as I just happen to have a RHD 100 jacked up at 
present. I remove a bolt to check. They are definitely 5/16" UNF but the 
length of the one I checked was 2 3/4" long. I guess that either this or 
a 3" would be OK.

A LHD would be around 2 3/8" or 2 1/2" long.

When I was based at BMC Service the standard fixings were only just 
coming in. There was a lot of work going on. For example the Morris 
Minor numbers has all been six figure numeric only. Most of these were 
changed to AAAxxxx numbers. Also the same part used by Austin and Morris 
would need a new number so that duplicated stock was not held. It does 
not surprise me that a few fixings that were not used in high volumes 
ended up with Austin style numbers.

One also has to add in the rivalry and vested interests that existed in 
BMC at its formation. 55 years on I have friend who was a Morris 
apprentice. He tells me that there was never any really good 
relationships built up with Austin apprentices. This was no doubt 
another reason why BMC went through a variety of mergers but failed in 
the end.

All the best
