Accessory Belt length

heres what they should look like..




the crank pulley can be this one or just a single groove pulley for what you are doing..



here is how the belt should run.
just ignore the power steering belt if you don't have it..




Joe, look closely at his picture - he has the old 69 and earlier style engine with the cast iron water pump and bell shaped W/P pulley... (Edited to say w/p pulley instead of alt pulley)

The stuff that you show are for the 70 and later set up with the aluminum water pump...

He should get the proper alt & pulley config to work with that... He has the proper pulley for the 69 and earlier config...
