One of the things I still had on my to-do list was making an adapter to fit the 4-hole water pump on the A112's block. After first having visited all metal and construction companies in the area, it turned out that no one had a scrap of 10mm thick aluminium. Long live Google because I found Dutch company "Aluminum to measure" where I could have a piece of "Flat bar" made to measure (200mm * 100mm) from their stock. Today it arrived and I immediately started fitting and measuring, drilling, sawing and filing.
