Ron,
I recently bought a new MC from Vic. Brit. To my surprise, the new MC body
is cast iron, whereas the one in the car--I presume it's original--has an
aluminum
body. Dave Nock told me that the original part was cast iron, but both my brake
and clutch MC are Al. I'm confused, but I kept the new MC--it's Lucas brand,
BTW--
because I figure I'll need it sooner or later and I'm not a stickler on
originality.
Re-sleeving runs about $50-60/bore, depending on who does it (White Post is
outrageous!), plus a rebuild kit will run about $15-20. I think I got the new
Lucas for
around $90 on sale.
To possibly save yourself some grief later on, I'd at least disassemble your MC
and put
in a new rebuild kit if the bore is OK. I've had problems with the little seal
on the end
that seals the line to the reservoir going south after a few years.
