speedo-drive

Hi! So, I've made the wp48 conversion with the single 320mm disc brake, the brembo calipers and the excel rim. The whole front end from a 450 sxf ktm. Now I've got a problem that I didn´t think of: I've got an analog odomoter and a digital pick up (magnetic) wheel and spindle. There's no space...

It's 1300 miles since I fixed my speedo after it had packed up, when I removed the drive mechanism it was obvious why it wasn't working because the drive pinion was stuck fast in the gearbox due to a build up of crap and corrosion, a bit of work with some wet and dry, a new pinion and repacking...

I'm looking for a speedo drive for a Transalp 600, drum brake model though it's likely to be the same as later models. Does anyone know if a dominator one will work?
