Bolt sizes or part numbers please...
Like the title said, what are the bolt sizes or GM part numbers for the following bolts for a 4L80E application
1. Flexplate bolts (with HD flexplate and spacer, I think the old PN is 12553332 with the new PN being 11569956 )
2. Converter Bolts (6 bolt 80E converter, may be PN 11589040) (ARP 230-7305)
3. Dust Cover Bolts (possible PN 11516328 size is for sure 10mm x 1.5 x 30mm)
Dont know if I should go with all GM stuff or just grab some class 10.9 bolts in the right size. I usually default to the grade 8 equivalent variety.

This is a list of part numbers that I copied down, I don't know if they are correct or if any of the numbers have changed:
4L80E Conversion part number:
15000206 - Converter dust cover
12551367 - 6.0 Flexplate
12563532 - Crank Spacer
12553332 - Flexplate bolts (6 required)
15198439 - 4L80E Dipstick tube
15183801 - 4L80E Dipstick
15013290 - 4L80E Shift cable bracket at transmission
11589040 - 4L60/65/70/80/85E Toque converter bolt (6 required)
The tranny mount can be re-used because they use the same part number (15767858)

The converter bolt thread size is 10MM X 1.5MM. I think they are about 16MM in length. The factory grade is 9.8. I suggest a little stronger, a 10.8 is what I send with my billet converters.

Oh, and here's a little FYI... Thanks to EVILGMC for setting me straight, the flexplate has been revised and now comes with spacer and bolts for about 60 bucks shipped from GMParts.
Bulletin 08-06-01-023
GENERAL MOTORS: 2004-07 Chevrolet Express, Silverado 2500-3500 Series, GMC Savana, Sierra 2500-3500 Series with 4.8L or 6.0L engine and automatic transmission
SUBJECT: A rattle or knocking noise coming from the bell housing when the engine is at idle may be caused by a cracked flexplate. The bulletin states the noise can be pinpointed with a stethoscope or "chassis ears." The fix is to replace the flexplate. A kit is available (12621399) that includes the spacer and new bolts.
