That?s a great plan, like the idea, however the swap includes an M90 so no speedo drive..... it?s looking like a later rear axle swop with speedo sensor and a later speedo massaged into the cluster.

Im currently upgrading the gauge face design with embossing near the cutouts, so it will look even more proper. Changing to aluminum sheet aswell.
