4.0 master cylinder swap into 5.2

Hey guys quick question. I got a 94 v8 zj that needs a new master cylinder. I have a 98 4.0 parts rig that i want to pull the master cylinder from. I need to know if they are the same. The 94 is at the shop so i cant compare part numbers right now so if anyone knows it off the top of their head it would be greatly appreciated

Look them both up on www.rockauto.com and see if they are the same numbers.
