Default Nuts and Bolts of a 07 STi 6 Speed into an 04 WRX

I wanted to get an idea of what all I would need if I piece a 6MT package together separately. I need a better idea if I need Subaru specific nuts and bolts basically to attach such things as the shifter linkage (as I believe it is different than the 5 speed), tranny mount, and so on.

Below is what I will have purchased separately:
6 MT (includes 6MT Clutch Fork, Slave Cylinder)
Clutch Assembly, Flywheel
6MT Tranny Mount
Automatic Driveshaft
Axle stubs, circlips, and axle seals
STi Short Throw shifter linkage


Any feedback would be appreciated.

You don't need to replace the clutch unless it needs replacing. Your current clutch parts will work just fine. Your 5MT Slave Cylinder will work fine too. You do need the fork though.

I did this swap not too long ago. Using the 5MT clutch, 5MT slave, 5MT TO bearing, and clutch fork pin.

Price no object, the STI clutch is a fine piece. You don't HAVE to install it though.

I used a 07 sti drive shaft cause its alittle thicker then my old wrx drive shaft and all I had to do was drill out the holes on the driveshaft part that mounts to the diff and I was good to go. I just had to drilled the holes outward enough to line up with the diff....

Not really as ghetto as you might think. Its working for me great.

I am not sure about the legacy and forester driveshaft, but I believe that any automatic tranny that mates to an R160 Rear diff will be a direct bolt on, but definitely try to verify.

Still any idea of ACTUAL bolts, nuts, or washers that I will need, that I cannot reuse from the existing 5mt?
