1.0 Part is perfect, 4WP not so much.

The Crown Master cylinder is a great part, fit well. Works well. 4WP, took several days to ship. Took almost 2 weeks to get to me, mind you they have 4 stores in my state. When the part arrived the box was completely destroyed and open on both ends. USPS had to wrap it. I called 4WP and they were very rude and offensive and insulted me about my "old jeep"

5.0 Jeep CJ5 master cylinder

Had to slightly enlarge the 2 mounting holes to accept original bolts, otherwise perfect fitment and works very well after bench bleeding.
