After a bit of a hiatus, I can safely say it's nice to be back in the Manroom! It was time to finish off the captive bolt brackets I'd made for the shock and pedal box mounts so I primed them before giving them a coat of satin black. To be fair I could've painted them any colour as they'll be inside the bulkhead or hidden behind the subframe but black was what I had to hand.
Next up was sorting out the speedo gearing as my plans had changed since I had the gearbox refurbished by Guessworks. Using his excellent speedo drive calculator http://www.guess-wor.../Tech/ratio.htm I worked out I needed a worm/pinion ratio of 5/17 as opposed to the 7/18 that was in there. Having already acquired the bits I needed it was time to remove, replace and refit. I checked my gasket box and made sure that I had the appropriate replacements, then whipped the speedo drive endplate off. Off came the cover and the part that the cable attaches to. A bit of gentle persuasion had the old worm and pinion out and on the bench. I gave the (already cleaned) replacements a blast of carb cleaner, then after drying I gave them a smear of engine oil. Then it really was a matter of "refitting is the reverse of removal" with the exception of replacing the gaskets.

These needed to come out!
I don't need these ones anymore...
New ones installed...
...And all back together as if nothing happened.
