Guys,
I drove my Harrington LeMans to St. Louis last fall for the United. It was 
about a 5 hour drive from Dayton. My LeMans performed wonderfully and the OD 
with 3.70:1 rear end purred like a kitten. I was passing traffic and could 
maintain an easy 75 - 80 MPH cruising speed. It has really made it a fantastic 
car to own and drive. My Harrington Alpine also has the 3.89:1 ratio with OD 
and it performs just as well and I'm putting an OD unit into my Series II with 
this rear end radio as well. This conversion is a MUST for anyone with, or 
considering, an OD unit. - Ian

Eddie:

Tony Leeming, on Gabriola Island, had a Series II in which he installed
an overdrive with a 3.89 rear end. Tony swore by this combo, and said
the ratio was just great for highway cruising. He has sold his car, and
is now working on a Triumph Stag, but I am sure if you contact him,
he'll tell you the same. He's at tleeming@island.net
