#1 Early drive shafts

I’m stripping my early S1 tubular driveshafts.
Can anyone advise as to the function of what appears to be a central pin located in the driveshaft...seems to be held in place with a circlip either end?
Do they need to be removed /serviced for any reason or can I just leave them alone and carry on with replacing the UJs.
Thanks

Hi Robbie...have a look in the factory fit 3.8 section page 10.. here is some info copied from there
Up until about July 1962 half shafts consisted of a steel tube with a yoke welded on either end. There is a 5/16" steel rod running through the centre, secured at each end with a copper washer, a steel washer, and a circlip. Later cars had smaller diameter solid half shafts:

The function of the steel rod is a bit of a mystery but the combination of copper and steel washers suggests it is prepared for rotation of the yoke so is probably a fail safe in case of a fracture in the shaft weld. It would prevent the parts flailing about which could cause major damage:

Images havent copies but you can see them in the factory fit section....Steve
