[Roadsters] 4 speed vs 5 speed

[Gary and Cindy Ault]

Dave,

Probably.  At some point, Nissan extended the opening in the top of the 
trans tunnel so it could accept either a 4-speed or a 5-speed.  Not sure 
exactly when that occurred.

Another issue is the speedometer connection at the transmission.  If you use 
the same mounting for the rear trans mount for the 5-speed as with the 
4-speed, the 90-degree adapter will not clear the side of the trans tunnel. 
A friend has an early '67 1600 with a U20 and 5-speed.  The PO who installed 
it drilled a ~1-1/2 hole in the side of the trans tunnel to allow the speedo 
cable to be connected through the passenger compartment.  I am told that you 
can make the 5-speed work by lowering the rear trans mount bracket so the 
top bolt holes in the mounting bracket align with the lower captive nuts in 
the frame.  Can't say for sure, though.

Those reasons, and the fact that it will be difficult to get factory-type 
trim -- you'll need a shift surround form a '67-1/2 2000 -- that I left the 
4-speed in my '66 1600 when I put in a U20 motor years ago.
