dfifferent distributors

[tonyabacus]

Does anyone have the measurements for the Lucas 23D4 and 45D4 distributors.

I note that both were fitted to the twin cam, but wondered what the overall length is including distributor cap. Getting at the cap appears to be easier with the 23D4 so why did Lotus make the change from one to the other, and is one slightly longer than the other in total length including the gear, or is body slightly different in lengthe?

Tony, in service I think they were always 23’s and only after production ended, and 45s were the then ‘current’ Lucas offering, were switchovers made. Yes, the 45s are taller and more awkward but I no longer have a 23 to compare.
