I'm parting out a 1987 325i (M20B25) that should work for you. Just pulled engine last night, still have to detach tranny and pull pedal box. I have everything you need - pedals with clutch master, clutch, pressure plate, flywheel, clutch slave, clutch line, driveshaft, tranny, shifter+linkage with good bushings - replaced 4 years ago, rad (although I suspect rad has a small hole and would recommend getting new or finding a better condition used rad)
Clutch was done about 4 years or 50 000 km ago. Felt great and expect it will have lots of life left. I'll check how it looks when I separate engine and tranny.
