Actually around 0:45 to 0:55 I'm testing out the speedo. It works. I combined the Ford end and the Datsun end for my cable, but I have heard that a straight datsun cable will work. I didn't really check it against a GPS speedo but it seemed about the right speed driving around base housing. It's -6 outside, with snow on the ground, and has been in the teens during the daytime the past week so I haven't been able to drive around at all. I'm also working out a pretty good exhaust leak on the driver's side header. I went ahead and had the driver's side header milled flat and I'm now awaiting a set of Percy's dead soft aluminum gaskets before I reinstall.
