The Imp trans is all set up for a hyd clutch making it just about perfect for a 76-77 LUV, but the 80 LUV will have a cable clutch and create some headaches making it all fit together. Not that it can't be done, it just isn't a direct, bolt in, hassle free swap.
I actually have the same trans sitting waiting to go into my 77 when I get some time.
