[TR] TR 2/3 steering boot - another question.

[Angelo Graham]

Hello List:
Further to Chris' question about the steering boot, I have mine in place 
with a hose clamp as well. I have a 5/8" hole right beside the larger 
steering column hole in the bulkhead. The boot does not manage to cover 
this hole. Just wondering what the hole is for? I think I have all the 
bulkhead connections made - tach, oil line. speedo, etc. I don't 
remember what this hole may have been used for. Any ideas? Just plug it?
Thanks in advance.
