What track bar are you using?
Remember your thread here:
Remember I suggested the Currie TJS or TJJ model? One of the reasons for that suggestion was because they use a 5/8" bolt, which is considerably larger than the 9/16" bolt. Drilling out to 5/8" would have eliminated the egg shape, and you wouldn't have any issues.
Replacing the bracket is a big process on the front. You gotta cut it off, which ain't a walk in park. A replacement stock cast bracket is not available anywhere that i know of, but I haven't looked hard because it sucks.
If I was going to replace that bracket I'd use a double shear mount that puts the bolt horizontal, instead of that funky stock single shear vertical crap. That then necessitates a custom made & bent track bar, with whatever flex joint you want to use in double shear. Some folks seem to use the new 2" Currie Johnny Joint's originally designed for the JK.
