Greetings,

Installing a twin turbo kit on my 2000 Silverado so I have to swap from my ICT Billet alternator/power steering pump bracket to the stock one. I'm wondering if anyone knows what size the four bolts are that mount the bracket to the engine? I found the bracket in my parts bin but the bolts are missing. I have the bolts that mount the alternator to the bracket but can't find the mounting ones. Thanks in advance- you guys rock!

 

They're 10mm "standard" thread (not "fine"), whatever that is; 1.5mm I think. They should stick out about 20mm through the brackets.

 

For future reference for anyone else who needs it. M10x1.5 115mm length!

 

Note also while you're at it, since that looks like it was looked up from a parts catalog:

The stock bolts have an unusual rounded tip without threads, maybe only 8mm diameter, and at least 10mm long. Not sure how that's accounted for, or not, in the "115mm" spec.
