dear seat belts
thnx for the update ...
well done ...love to see right done right
metric is metric and cross overs will likely not work ...
the metric thread can be so minuscule as not to matter by the eye ... but
matter a great deal
just like an ear knows whose finger is in it ... so does the metric thread
...
if you are having a hard time in your neighborhood finding metric ...then go
online and the parts can be ordered from canada or a specialty shop
yours
