Bolt length/thread pitch...

[Smokin04]

I'm trying to figure out what the length and pitch is on the bolts that hold the differential caps down. I thought it was 2.5 x 13 TPI, but I'm not sure. The overall length is 2 7/16"...I think. Can anyone correct me please?

Also, what are the dimensions for the IRS cover bolts? Thanks for any info...
