Belt sizes for 360 with ac and ps?

[Gettysburg150]

Hello all,

Finally got my engine running. Need to get new v belts. There seems to be a lot of different options.

Anyone know the size belts I need for a truck with ac and power steering? I need the alternator belt and the ac/pa belt. Just a plain 2 v-belt system. Thanks

There were quite a few a/c set-ups offered through various dealerships back then. Several compressor/ pulley combinations, hence there are alot of belt options. ideally you have the old ones and can take them in to get matched up. otherwise might have to find the option closest to the middle of length range and try it and go from there.
