Along these lines.....I have an A type OD that came out of a 4A that I am
putting in my 250, but it doesn't have the reverse light switch. I have a
switch that I can put in, and the location is the raised boss that is cast
into the cover plate, but....
What is the drill and tap size that I'll need to use to install the switch?
I'm sure someone out there has done this before. Any help is appreciated.
TIA
Mark

My A-type works in 2d with no problem. I think the only issue is the switch
in the top cover to allow it actuate. There are plugs to drill out to put a
switch in. Now on the other hand I really haven't found it real useful in
2d.
This A-type is in a 6.

Subject: Overdrive on 2nd Gear
Listers,
I am currently involved in building a lightweight overdrive gearbox
based on the early Herald/Standard 10 all-alloy casing. The 948 gearset has
a wide gap between 2nd and 3rd gear, but in other respects is ideal,
allowing us to fit a higher ratio final drive without losing flexibility
lower down. Is there any way we can use the overdrive (D-type) on 2nd gear?
I'm aware that Overdrive pressure is dependant upon the gear speed, but I
remember some of the earlier TR's had A-type overdrives which operated on
2nd. I also knew a guy years back who had a Vitesse 6 with the switching
modified to work on 2nd, but I don't know how succesful it was. Our other
concern is whether the overdrive would handle the torque produced in 2nd
gear.
The engine used is an SAH tuned 1147cc unit with a single weber
(type?). The vehicle is a 1964 Bond Equipe 2+2, weighing around 13cwt.
Any advice will be appreciated,
Cheers,
Bill.
