hey there guys i have a 1998 mustang gt with a custom roof that doesnt sit quite right, but latches perfectly. my mechanic and his pals advised for some hood pins. i was informed of peoples roofs flying up hitting the windshield while driving. i was told it was my call because well the holes are permanents. theres no way to undo it. so my questions is; should i get them? why or why not? also 87, 89, vs93 octane gas? my Lucy Ford has over 300 hp is growl is very low and heavy. i feel like i need to treat her right. but will the extra .20 per gallon make a difference? today i put the middle grade (87) from Clarke's and i felt a difference. i was amazed. i will be driving some in the chicago cold. thanks for any input.
