Hey Pat, did those measurements for the trailer hub wheel stud give you what you needed? Knowing how it worked out could help others checking fit on the same part.

@JesseM No they did not. i did find some that worked though, although I'd be happier if i tacke them in place from the back!

@PatI Ah sorry to hear that. Glad you found something that did work though. And yea a few tack welds could definitely grant some peace of mind but as long as your lug nuts stay torqued to spec you shouldn't need to worry about it too much.
