'69 small block - correct alternator belt

[sftibbs]

For my '69 SS350 with AIR pump, water pump, crank and alternator, my research shows one belt around all four pulleys. If this is correct, does anyone have the part # for the alternator belt? I have seen #3883248 but it doesn't specify if it is for AIR or not.
Thanks for any help.

P/N 3883248 is the correct belt for that 4-pulley A.I.R. application. GM discontinued that belt from Service decades ago, but there may be a supercessive number. I use Goodyear "Flextra" #13465 on my '69 Z/28, and it works fine.

Thanks for the help John. There's a repop at Heartbeat City with that number on it...may do the job. If not, I'll try the Flextra.
