85 Mk2 transmission swap

[Mike 65]

I am not so sure that you are going to find too many salvage yards that still have cars from the 80's. But, you will need
the trans and clutch assembly
shifter and linkage
the pedal and all associated hardware
The trans mount might be different so grab it just in case
You'll also need a wiring diagram to deal with the trans computer that is currently interlaced with the ECU and speed control computer
The starter wire also goes through the tranny and that will have to be corrected.
