I made new ones from G10 fiberglass. see
<http://www.wbryant.com/StellaBoat/hauls/0811/k011.jpg> G10 handles
compression loads very well. It has held up for 7 years, and I don't
see a problem. If yours are wedged shaped, machining the material to
fit can be a challenge. Also, if your 'spacer' cracked it may have been
because it was bridging over a gap or uneven spot in the bilge. G10
does *not* handle that kind of stress well, either. I broke one of my
little spacers because it was supported on the ends but had some air in
the middle around the bolt. I made a new spacer, set some epoxy
thickened with colloidal silica around the problem area, and put the
spacer down with some waxed paper underneath to avoid epoxying the thing
into the boat. I used the nut to press the spacer into place and ensure
that it was aligned right with the bolt. After everything cured, I
pulled it up, and when we set the keel for good we caulked the living
heck out of it.
Note that I didn't have the spacer things before. I set them there to
keep the nuts and washers off the bilge floor, so they wouldn't sit in
standing water.

Hello Listers, I was tightening my keel bolts on my 35-3 before launch when I
heard a crack.
