That car had the O/D manual trans removed and replaced with a regular 4 speed manual. They had optional drive gears for the output on the transmission speedo cable. I discovered eventually mine was the wrong one. I think they were color coded. The rear axle may also have been swapped on that car as it had been modified for rallying.
I listed this link for a Weber carb swap for a B18/20 and others for sale locally to me:
