I have searched and thought I had found the answer the other day but now I can't find them.

I have driveshafts from Jessie and High Angle Driveline on the way. I will be running a front CV shaft in the rear and a rear shaft up front. I know I need to swap the T-case flanges or double drill them. What about the diff flanges? Are they the same pattern?

You don't have to worry about the diff flanges. The bolt patterns are the same.

I (4RnrRick) am about 95% positive that these are accurate dimensions.

I read the FAQ and was pretty sure that it meant diffs were the same. Thanks for confirmation.
