To make the van more comfortable to drive at speed I am getting a custom diff made, with a ratio of 4.1 rather than the 5+ that is in there. I have chosen 'Dandy Diffs' in Dandenong (outer Melbourne industrial suburb) to make it for me. They had a beautiful lathe from the 1940's there, still in use. The owner picked it up for $1000 a couple of years ago. What a bargain! I guess this stuff isn't valued because the skills to use them are disappearing as fast as manufacturing in this great country.
That's my rant for the day.
