Thanks to Darrell Dick for providing information about where to source these acorn nuts on the Yahoo! MGconvert news group.
The two hoses connected to the transmission on the right side are secured in place with acorn nuts. The original acorn nuts were constructed from two pieces and were prone to leakage if they bottomed out on the posts when being tightened. The solution is to use two or three extra crush washers to prevent bottoming out. If yours have already been turned into leakers, then you need new ones. As an alternative to purchasing the same original design as NOS, consider part number AN-124 from Colony Machine. These are chrome plated and while I would rather have stainless steel, I've been unable to source stainless steel acorn nuts in the required size (12 mm × 1.25 mm). I purchased these acorn nuts on eBay.
