[Alpines] rear axle question

[Tony Lang]

Yahoo has changed so much I'm not certain to whom I'm actually addressing BUT
here's what I've learned about OD. The speedo cable that's to short is for a
non OD car- OD uses a longer cable. Pitt falls is the switch oppsite the
signal switch which engages the OD. There is another on the tranny  that
disengages OD when not in 3rd or 4th gear- reverse will tear it up. There is
also a unit on the firewall- not positive the name BUT I need one if anyone
has a spare. I have a S5 with OD and it absolutely screams on the interstate
but I lost a bearing cap and haven't fixed it yet. In my opinion if  you can
find an OD unit, you will love it- I wonder if the stock rear end gears would
still produce plenty of power and better gas mileage- guess you give up
something when making changes. Happy Holidays to all.

I have never seen any step-by-step guide to add an OD. I have one in
place
but engine still out. Is there any major pitfalls I should be aware of?
And
how to lengthen speedo cable, std is very tight when fitted to OD unit?

rear axle question

Hello all,



I just read the article in this month's
Rootes Review about adding and O/D
unit, and they listed two different rear
axle ratios, and the resultant
speeds v. revs.  I always had these questions:
how do I know which rear end
I have, and why were there two different ones? 
At one point I thought one
went with the O/D trans, the other with non O/D,
but that made little sense.
Can anyone 'splain'?



Thanks, Merry Christmas &
Happy Holidays to all,
