I presume I have the same set as well. Good snag
Only tips I would suggest are:
-Start w/ the brake pedal. Yes it's the hardest (physically and otherwise) but it's also the one w/ the least forgiveness. You'll need to line that one up perfectly and can then align the clutch pedal off of it. If you do clutch first, you could run into clearance issues on the nuts for mounting the brake pedal.
-If your hardware didn't (or even if it did) come w/ lock washers, I'd still hit the threads of the machine bolts w/ some locktite. Definitely don't want thos suckers coming loose while driving.
Good luck and enjoy!
