Also known as part# 311 198 069/87.

Some early blocks (like single relief blocks) require the lip on the bottom of the cylinder to be filed off. The lip is very thin and so easy to file off, it'll take about 5 minutes each cylinder if you do it by hand. Or you can use a dremel and a grinding disc and do it in 1.
of these to my order now.
