## Questions & Answers

**Q: what is the outside diameter of this pulley?**
A: 3-1/2"

**Q: Came whit bolt**
A: Yes bolt wa last included

**Q: Whats the difference between this and acdelco 36299 ???**
A: I'm answering too late to help you, but maybe someone else. AC Delco makes most, if not all, of their parts in two grades. Exact OEM replacement and OEM spec. The difference  (supposedly) is that the exact OEM replacement is the same part as what G.M. uses (used) and as a result more money. The OEM spec is built to be a direct replacement but may not meet all of G.M.'s stricter specifications and is cheaper.  My personal opinion is that they probably are made on the same assembly line and you're paying extra for a better warranty (read: insurance). Or it might be possible that the OEM spec ones fail some inspection points and fall just outside G.M.'s requirements, but will function just fine so they sell them for a bit less. It's one of those chevy versus GMC things. Same truck, one is dressed up a bit nicer.

**Q: Plastic or metal**
A: It is METAL plus it has the split washer that holds it securely to the mounting bolt, and you should follow the torque specs when you replace it.
