My 260Z started life with a 4-speed manual. In the early 1980's, a new engine and a used 5-speed was dropped in.  The 5-speed began having problems and was beyond rebuilding. I tried to replace it with another 5-speed and it was too beat to be rebuilt. I attempted to get the 5-speed up and running with some components out of a 4-speed but the gear lash made more noise than my exhaust so I went with another 4-speed I purchased for $23. My car is in the shop for the next few months waiti
