Default A/C delete belt size?

Anyone happen to know the size belt I’d need between just the balancer and water pump when I delete the compressor?
’71 small block.
I can measure it by trial and error but I thought maybe someone might already know…

Unfortunately it appears a previous owner put a March under drive pulley on the crank. It’s 5-5/8” OD instead of the stock 6-3/4”.
So, looks like I’ll be making several trips to the store and some trial and error. Compounded of course by not having any adjustments to this arrangement.
