alright - this might be a stupid one.

do ye of the tron repair/service squads use actual BA tools/sockets?

are these obtainable at reasonable cost in the states?

if so, where?

are there certain sizes that a tron serviceperson should/must have?
[rather than a huge full set of sockets]

googling finds some large sets, but they aren't cheap, and almost all
are in the UK, thus adding to the cost significantly.

thanks in advance folks...

corners of some nuts/bolts by using the wrong size socket...]
