This acquiring of new $3 bolts sounds like a viable option more in step 
with my somewhat limited income...

Hmm - guess I'm gonna have to get another part time job, the one I've 
got now is coming to an end soon...

Ah ha, that's the one thing that kept me from ever getting very familiar 
with the two Rabbits I used to own...

I've got a partial Mitutoyo micrometer (scrounged at the local 
scrapyard) that reads in thousandths - I'll have to see if I can adapt 
that some how...

Thanks, and thanks for your response and recommendations.
