Just for reference, the bolts sizes you would be looking for are M10x1.25 x 35mm long. If they don't have metric then a 3/8" x 1.5" long bolt/nut combo would work as well.
I ended up using the top bolts from the header/hfc flange, worked like a charm, THANKS!

Everything went smooth tonight. Drove a couple miles. I like it, not sure the GF will be thrilled, but that's to be expected.

Is there a typical break in period for these? I plan to go to the 1/4 mile track Tuesday. Should I have a certain amount of miles on them before I go race?

Also, this ties in with the previous question, how long till the ecu "learns" and gives me my best performance?
