Ahh, is THAT what it's called. Yes, they are splined. The shop that got
the old ones out for me was apparently able to get them out without
making the holes too big to grip the spline--I'd be careful about that
if you're drilling them out. Pretty heavy-duty little suckers,
too--though short, they weigh several ounces at least (3 of 'em,
anyway). No wonder they were some $7 each.
