Crank sensor bolts
Odd... Mine must not have been tapped deep enough cause that length bolt left 1/8" of slack when bottomed out. You could always stack a couple washers on it, though. Yet another reason to test-fit every part before final assembly...

Thanks guys, obviously I meant knock sensor bolts.....
I've probably got a couple flange head bolts that will work.
Does the mounting surface need to be bare metal? I painted the block.

That hole should b drilled 22 mm deep and threaded 20mm as per a service manual I have on an lq4 block. I actually bought a button head bolt at 20mm and fits fine. Maybe it's a Lil different length from block to block or alum to iron block?

Code:
Crank Position Sensor The crank position sensor (GM P/N 12560228) installs into the block's right side, in line with the reluctor wheel. Lube the sensor's O-ring lightly with oil and insert until seated. The sensor's bracket tab is then secured with an 8mm x 1.25 x 10–15mm bolt (this is a blind hole, and the bolt will bottom out at a depth of about 19mm).
Unless, of course, he's dealing with a 2006+ block.
