Small Block & Big Block Chevy Specific - serpentine setup 350

I have a 95 z28 that i pulled the lt1 out of cuz it looks like a grenade went off inside of it and now im putting my SBC into it. Im trying to find a belt setup that only does the alternator and P.S. pump. Im getting an electric water pump and i took out the AC. Any suggestions as to wut i should get or where to get it? thanks...

If you are using the stock system like i cam going to do, i am using the AC, if you are not, buy a AC deldte 1LE bracket from Ebay, it will allow re use of the stock sozed belt.

Or mesasure the total length by a flex measuring tape and go but that size.
