Before today, I was always unhappy with the fact that the people who installed the manual trans in my car just hacked holes in the floor for the linkage and didn't do it "right." After today, I'm a little more tolerant. First thing was to test fit the new Sherman four-speed hump and of course, it didn't fit right, so I spent some time with hammers, vise (as a sheetmetal brake) and pliers to get it to fit better. Once I got it close enough to be able to bond, I started cutting out some of the old sheetmetal. I had intended to use the cut-off wheel on me angle grinder, but of course, the aftermarket wheel was too loose on the grinder, so I resorted to sheetmetal snips. That was hard work. Gonna look for the right cutoff wheel or, failing that, some nibblers.
