It's a Craftsman moulding blade, 2 inch PVC, 3/8 all thread, modified 3/8 coupling combo. The modified coupling is half ground away, heated with a torch and bent to fit under the IMS nut to pull the bearing out. I was in a hurry or instead of the ground out coupling I would have made a fitting with a 3/8 thread on one side and the IMS bearing bolt thread on the other side. It's cheap and I was just playing around, but it worked well for me. If I were more serious I'd have found the proper tool, or made a better one. So it's up to you make your own tool or buy one. I'd be very squeamish about using a tool that pressed on the engine block, it's just thin section aluminum and you'd stand to damage it by pressing on it to pull out the IMSB, the forces get quite high so press on the face of the intermediate shaft. Best of luck!

Thanks! I like your style!
