belt size for underdrive pulleys?

[Zozma]

So I managed to dig up a underdrive crank pulley and a overdrive alt pulley and I wonted to install them but I don’t know the new belt size. I searched the site but all I found were old post saying to go to underdog performance but the site is shut down so that’s a no go. So can any one tell me the belt size I need?

I just installed the crank pulley the other day, but I got the Auto Specialties pulley from summit, it came with a part number for autozone.

That size, underdrive crank with an overdrive alt, the other two are the stock size

^ lists gatorback belt #4060872. That would be a good starting point for your size search. The last three digits of the belt part number is its length, but I don't know if that is in inches or centimeters (probably inches). A good parts guy knows the deal.

They sent me the 4060865 and I've had it on for months no squealing, fits my truck perfectly

Where did you find the underdog pulleys? I could only find just the crank one from summit
