Right, Midwest has the highest quality kits like most all other injection shops carry for a little over $30. Looks like the exact same kit shown on Ebay above for $61, brand name Dipaco. And any time you can't find a correct cap just reuse the old one. Due to an ATS turbo installation and drainback line change I reused a right rear cap for over 12 years. If you live near a half way large town a local injection shop should have the Dipaco kits.
