I have searched the archives and have not come up with an answer to this question.

Was the original early 5 speed shift knob, that was used in markets other than North America the same size as the 4 speed knob we got here? I have read that the replacement 4 speed knobs are larger than the original 4 speed knobs. Is this also true of the 5 speed knobs or were the original 5 speed knobs larger originally? In these pics an original 4 speed knob is compared with a genuine Nissan 5 speed replacement knob. I haven't seen a comparison pic of an original 5 speed knob and a replacement 5 speed knob anywhere.

Ron,

It may not really address the issue, but my all original '70 SRL311 has a 5 speed knob that is the same size as an original USA market 240 4 speed knob. I'll take it off tomorrow and post a picture. Several parts are shared between the 240 and the late roadsters.

I'd stay with the 4 spd knob and make people look twice when you shift into 5th.
