Andy,
The S1 to mid S2 axles have 17 splines. All later axles have 25 splines up to
SV which uses totally different axles.
You can use coarse or fine axles, just so long as you swap out the spider gears
with splines to match.
This may have allready been done in your case.
Whatever axle you go with, I firmly recommend that you have your axles
magnafluxed if you are going to race with them. Racing puts a greater load on
the axle than even the most spirited driving, and the rootes axles are
notorious for breakage outside the rear bearing.

Subject: Rear axle questions
Hi, Alpiners:
This has probably been asked before so, please, bear with me. I need to know
what the difference is between the rear axles in an early Alpine and the same
in a later Alpine. I am building a spare rear end for my Series I vintage
racer and somewhere I read that there was an axle change at some point in the
Series II production run. However, I have a spare "tube shock" rear end
housing with axles in it and they appear to be identical to the early axles
except for the fact that they have a cotter pin hole in the threaded end,
presumably to lock a castle nut into place (the early axles don't have this
feature). Also, I checked the splines and they appear to be the same. I also
test-fitted the later axles to the early rear-end gear set and they fit just
fine.
Is the only difference the cotter pin feature?
Thanks,
Andy Walker
