I also got my hands on a shift kit and type 3 shifter.
You can see the type 3 on the bottom of the picture with the bent back rod and the pin to keep it in location.
This is the selecter rod from the Type 1.
This one is after i cut a slot for the T3 pin. I took my time to try and make it a nice snug fit. I used a 1mm cutting disc on an angle grinder.
This is how Ive tried to put the shifter in, I don't know that it is right. I think it was actually upside down, it was slipping into reverse when going for 2nd from 3rd previously. The metal tabs are bending down now.
Sorry about the photos, I only have my Mobile to take pictures with.
