I am in the throes of a Series 4 overdrive conversion. Could anyone please provide me with the original specified propshaft length for the overdrive car. I have measured two examples and they vary by 25mm! Thanks. Bob
Hi, As far as I remember the od propshaft for a serie 3a I installed on my car was 3inches shorter than the non od one. I hope this helps you and I will try to find the length of both propshaft. I have this info somewhere but cannot locate it at the moment.
The difference could be explained by knowing that the propshaft of Arrow-type with overdrive has a different lenght caused by the nose of the diff which is longer and the place of the gearbox/overdrive including the longer bellhouse of the Arrow gearbox. I know that the nose of the diff of the Arrow type cars is about 1 inch longer and if such a diff is installed on an Audax type car (like the Rapier series IV) than the propshaft has to be shortened by about an inch.
