[1968 GTO Resto-Mod]

i have been thinking about this idea for a long time, but i'm starting to feel like i'm floating in uncharted territory.

these are all 6 groove serpentine pulleys.
i still need a plan for including an auto tensioner and/or idler pulley.
i still need a plan for spacing out all pulleys to alignment.
do any of you guys have experience with "do-it-yourself" serpentine conversion systems?
if so, i would be very thankful for your input.
also, where else might i look to find information about this kind of modification?

of course, i still have all the original v-belt pulleys so if this serpentine conversion idea doesn't work out i can just reinstall the original system.
please feel free to share your thoughts... thanks!
