mr4-tc sp...
Sorry,
Did not mean to step on your toes. Anywho. I should carify one piont thought . The material i removed was from the yokomo spacer using my body reamer. You could possibly use something else other then a yokomo spacer (I.e. a used diff ring or something rigid and flat). Just use a stripped spur as a template for drilling the four holes.
i hope this helps.
