Seems that no one here has purchased an engine kit from lotus61963.

While we're on the topic, a rebuild kit is rarely neeeded for an A-series engine. Usually just an overhaul is needed -- Rings & Gaskets. Most times the bearings are just fine, you can check them with plastigauge. Pistons and oil pump rarely need replacing unless they are damaged. The factory service manual contains the procedures and specifications for inspecting them.
