I ordered this tool to check the bellhousing alignment on my Lakewood. The folks at Browell's probably don't sell a ton of these for Mopars so I had to gather a couple measurements before I could place my order. Figured I'd post about it in case someone else needs the info...

ScottSmith_Harms did a great job posting images and information about the tool and the bellhousing opening measurements here (Thanks Scott!):

The bellhousing opening is either 4.850" or 4.685"

The part of the Browell tool that bolts to the crankshaft is one of two sizes, either 2.160" or 2.043". The measurement is made by measuring the outside diameter of the "ring" at the end of the crankshaft. I have a 440 crank which measured at 2.160.
