i am installing some fender washers and allen head bolts in the center 6 holes in my plenum. the place im buying my stainless steel allen bolts from does not have the 55mm length specified for the front three bolts in my mrev2/spacer installation guide. i have the option of 50mm or 60mm. i worry that the 60mm bolts will be too long and bottom out, but i could cut them down if necessary. i worry about the 50mm bolts not grabbing at all. i realize i could order the "right" length online somewhere, but a local purchase is more convenient. has anyone used either one of these bolts on the front. any recommendations on either of those sizes? please let me know guys! thanks!

 

i only posted this bc i thought someone might know off the top of their head. ill answer my own question as i had time to mess with the car today, finally. i unscrewed one of the plenum bolts until it disengaged all threads. i had about .75" - .875" sticking out. 5mm is less than .25" so i figured id be fine with the 50mm bolts. ill let u guys know if it doesnt work out. im sure it will though.
