I pulled the downpipe and one of the bolts that attaches the downpipe to the turbo housing was a bear coming off, and a couple threads are sheared off. Anyway its a stock downpipe and stock turbo, and I'm looking for new bolt/bolts. Anyone know if I can get these from GM, if so what's the part number. OR if I cannot, anyone got a link to someone who carries them?

does anyone know the size and thread pitch for the dp to turbo bolts?
I'll double check tomorrow, but sure measures up to me to be a shoulder bolt w/ M10 x 1.5 thread, 12mm diameter shoulder, 50mm shoulder length.
Looks like I can get them from McMaster Carr #92981A407, $4.11 each.
Should work.
I'll double check the threadform at work tomorrow where I can do a better job of measuring, or we may have a ring gage. I'll let everyone know.

Guess you don't venture into autoparts stores....
Advance/CSK/Kragen, Autozone, O'reileys, Pepboys, RS Strauus, etc have a section where Dorman products are sold under the monkier Help! there they have odds and ends for interior, exterior, engine, and drivetrain parts. I bought these same bolts last year when I did a turbo replacment on my stock T.

Whatever you choose to install this application is a great candidate for plenty of Antisieze on the threads.

in most modern auto parts stores, the Help! section is the best place to look for the things you need to get your car going again, since the 16 year old behind the counter doesn't think that he needs to do anything or learn anything about the products he sells to earn that $7 an hour he gets paid.
i know of a couple of stores that have an entire aisle of Help! products, and i usually find myself just looking thru everything to see if i can find anything that will work for my cars. i have a pcv elbow on my Monte that i think was for a Mazda that i found in the Help! section.
NAPA doesn't have a Help! section, but they do have the very same products- with the very same part numbers- in NAPA boxes and a higher price tag than most other places.
