Here's what we have noted in the "Prod.Models" section of website -
Cushion, speedotachometer, vins 1 - 3433 - pn 37235-300-009, No "stopper" on cushion
Cushion, speedotachometer, vins 3434 - 7414, pn 37235-300-019, "Stopper" added to cushion to prevent speedo and tacho from rotating in clamp rings
As i recall, this info came straight out of factory parts manual.
The short answer to your question, Mark, is "Yes."
