4wd Engine Crossmember In 2wd Truck?

Im looking at replacing my 2wd crossmember with a dirty dingo 4wd LS crossmember.

Ive decided to build the complete front suspension (long travel) and i want to use the 4wd dirty dingo crossmember as a starting point. the DD crossmember bolts in the 4wd frame.

does a 2wd frame have the same frame holes as a 4wd frame? will it bolt in or would i need to drill holes?

This is on a 3/4 ton frame
