I really can't say definitively if a different speedo is needed or not for a 4
synchro. For the 3-synchro the gauge is the same OTHER THAN THE INTERNAL
GEARING which is only about 5% different - a difference that one could come out
with from the wrong tires. Anyhow, like I said, I am not sure with the 4
synchro - but I would suspect the same. If you want to know and don't want to
look it up call Noisenger or that place in california (can't remember their
name, they both advertise in Hemmings). Be sure to ask based on year, model
with OD vs. not, and if the internal parts are EXACTLY the same, or just close
to the same.
