1972 SE5A, manual overdrive; what type of prop would you expect to be fitted? I have a one piece unit with no sliding joint in it which puzzles me. Is length change with suspension movement supposed to be taken up in the gearbox output spline connection? Just seems a little wrong to me smile

i have the same, i think because it works around such shallow angles the length is taken up by engine mountings and suchlike

IIRC the only 2 piece props were used on the later 6 series - and even then half have probably been swapped to a one piece - one less joint to spend money on! I think the fixed mounting point halfway down the chassis meant the 2 piece had a much more acute angle and increased range of vertical movement than the longer 1 piece.

I changed mine on a 6a when I swapped a type 9 5 speed in.

Should be LH-type overdrive with a prop that is a splined push-fit into the back of it - which is where you get the travel to accomodate suspension movement.

If it's a "re-dated" (i.e. 72 VIN plate) 73 on SE5a, then could have the flange mount prop on the overdrive in which case there should be a sliding joint built into the prop. Split props were never fitted to 5a's
