I made these a few months ago for a GL4x4 member that, obviously did not really need them.
Because I still have them
They are A-2 (not yet heat treated) Air hardening tool steel.
I do not know the proper application for the given sizes, but I figure if you need them, you'll know.
All are 1.250 I.D. X 1" thick.
The O.D.'s are caliper dimensions as I do not have a Mic at home.
They are held to .0005 of the bearing dia. that they are intended to replicate during alignment.
Material cost was $95 only because I didn't have to pay a cutting charge (took a drop)
My understanding is that these sell for $99 a pair from the various Mfg.
$150 will make them yours. Not to include shipping........But that can be arranged.
