I would like to use new fresh bolts and nuts close to original or original would be nice on my accessories like, power steering brackets, alternator brackets, water pump, thermostat housings and so. Also would like to find good original or close to original spark plug wire loom set, I'm looking to keep it stock looking as possible for same year. Well while I'm asking , how bout the same for after market and or new stock exhaust manifolds too. I can't seems to like zero in on these parts with out going all over and scratching my head Any help with suppliers that sell these stock or close to looking stock parts that you folks out there may of used or can recommend would be greatly appreciated.
Thanks for your time and help.
