this is for anyone who is going to buy or has a siebon carbon fiber hood. i just got my hood in yesterday, shipping quality was great well protected, the hood is perefect, solid exactly what i wanted. however the hood latch bolts they included were size 10 and would not hold tight, luckly i have immediate access to a fastenall wall of every bolt or fastener i could imagine. i replaced the size 10's with 11's and have no worries. im positive had i ignored this or not caught on the hood wouldnt have lasted 5 min on the interstate. hope this helps someone.
