I think I may have achieved Grand Guru status!

I have had a win drilling and tapping the rear or the extension housing and fitting a new reverse switch. It is actuated by the END of the rod which normally strikes the side of the factory switch

Slapping a B310 5 speed into a 1200 or 1000 is not real difficult but the clearance (or lack thereof) for the factory reverse switch makes keeping the switch a real pain.
there are generally 3 options:

1 plug the swich and mount a new switch
on the dash (dodgy)

2 plug the switch and fit another next to
the gearstick--ala Levey

3 take a 40 mm hole-saw to the side of the tranny tunnel and screw in the switch after installing the gearbox

or drill and tap

the switch I used is from a landrover, It is 9mm diameter and has 20mm available thread
thread is 3/8UNF 24tpi
Cost a huge $20 AUD

I have only experimented with a FS5W60L dogleg box but it should work on the FS5W60A box as well however a relay would be req because the operation of the 60L & 60A switches is different

PS while hunting for a suitable switch , I found a replacement for the Suzuki Sierra which looks identical to the factory (Niles) switch on the dattos
Also $20 on ebay

win and win.

you should make up a How to and post it to the wiki.

Nice work. Got any pics for me to perve on?

Thats great news Mal, good job! :)

nice wok mal ! ,have you had a chance to check it with the box in a 1200 ?

Nice one! A problem I hadn't gotten around to thinking about yet, I have a switch mounted in the cabin like Levey. Got the same gearbox as you so I'm very interested in a how to/ parts list! A photo of where the switch goes and part number/ description of the switch would be enough.

Dylan-- PM sent

the switch used is available via ebay (Australia) from seller clr4wd
part # R575166
just search "reverse switch landrover"

hey mal would you happen to know where i can get the standard reverse light switch for the 4 speed?? mine is knackered

PS while hunting for a suitable switch , I found a replacement for the Suzuki Sierra which looks identical to the factory (Niles) switch on the dattos
Also $20 on ebay
Joel-- have a look at the suzuki switches on ebay
or visit a suzuki dealer to confirm compatibility

alright no worries i can do that... cheers for the heads up mate

Good work Mal you five speed god you!

I'll have my gearbox out in the coming weeks will definitely fit one of these. Thanks for the info.
