Great thread NSFW! Much more organized and more detail than the "Master" thread. I'm trying to make sure I have everything before installation, so I have some questions about these small parts. I'm also getting 05 STI parts with Spec B axles, so it should be similar to your experience.
You say 04 6MT needs new front axle seals, but the post with the part numbers says for 05. Did you use these seals with your 05?
You say 6MT for your list of small stuff, which I assume means STI is ok. The "reverse lockout cable" appears to be Spec B only, but the "downpipe support bracket" looks like STI and Spec B is the same part. I can't say for the clutch fork shaft plug and spring, but they're only a few bucks new. If I needed to buy the Spec B shift linkage new, do you have a part number for that? And the shift boot?
Any other small things you may of left off? Thanks again.
