I understand that these bolts are TTY and should not be reused.

Extensive searches have been fruitless. GM OEM parts sites tell me that these bolts are not available, that they have been discontinued.

Surely someone, somewhere supplies these, as there must be a ton of the 4.2 engines out there yet.

So, where can I find them?

The part number for the variable camshaft actuator sprocket bolt is 24100263, and the part number for the regular camshaft sprocket bolt is 12565425.

The 2410063 bolt is available from numerous sellers on ebay general motors 24100263 in Parts & Accessories | eBay beginning around $8.65 a bolt.

The 12565425 bolt is available from rockauto.com (GENERAL MOTORS 12565425 Bolt | RockAuto) provided you buy 10 of them at a time, and they are available on ebay individually from several sellers beginning around $5 a bolt: general motors 12565425 in Parts & Accessories | eBay

I believe both are also available from GM Parts Online - Buy OEM GM Parts direct and save up to 40%

Good Luck!

Part numbers... just what the doctor ordered! I performed a general search on eBay earlier, that only turned up used bolts. A part # search turns up tons of them. Order has been placed and they are on their way. Thanks a million!
