UN1 Rod Change Reverse Gear Lockout

Having had a look around without any luck, does anyone know where i can get a reverse gear lockout plate/mechanism. Reverse on mine is left and back. I have seen the Tornado cable mechanism, but would rather a selector guide plate incorporating a reverse gear latch of some form.

Any ideas?

Mick at Southern GT makes a cracking gear shift with lockout plate for the UN1 rod system, work of art.
i know. I have seen it :). But I have all the rod shift, etc. all I would like is the lockout plate to alleviate the problem.
~It is also "upside down".

Brian Magee made one on my car
Simple aluminium bent to follow sill shape
Hole cut in middle
And a lift over spring held gate

I’ll take pics

thanks Ian. That gives me some idea for something I might be able to knock up. Or have a chat to Brian.

Following the above.... Has anyone made a lift-up type lock out function, similar to those used on lots of modern cars?

This is mine - it's a UN-1, so same shift pattern as yours. I kept the overall look of the original GT40 lockout with a lift-up mechanism, though of course reverse is left-and-back on the UN1 instead of left-and-forwards like on the ZF-equipped cars. Still need to polish out the *machining marks, but I was just testing for fit, function and alignment.









*Getting a ot of tool chatter, even on the lightest of cuts, on my tiny Hobbymat/Prazimat milling machine. After 34 years, I think the spindle bearings are on their way out....!

That's a lot of machining there.
 
I have the same gearbox in my lotus europa and made this, inside on the left is a black nylon spring loaded block that stops the stick to go sideways, the little pin on the side can be pushed forward 1/2" the free the stick, when I go back to first the spring pushes the nylon block back into position. btw I can use the stick and the pin with 1 hand
