The unit is 3k. Just one of the reasons I have 2 jobs. The driveshaft cost $225., balanced, painted and w/ new U-joints. They provide an adapter for the speedo so I didn't have to get a new cable, but I did since mine was due to be replaced. I got a shorter one which does fit better. The synchro really isn't needed between 1st and 2nd since 1st is rarely used. When it is, I'm going about 1-3mph up a ramp or a hill.
