Just went through the exact same thing. Best of luck.... Only solution I found was getting custom studs made. I searched for DAYS. Custom ones are an exact match to the originals but 3/8" longer in the non threaded area. expensive but couldn't find another correct option.

EDIT- also these have all the right specs... But the picture is not correct in what you get anywhere even on Dormans website. The knurling is completely wrong. It will not connect with the hub flange, its a course knurl ours is like a fine knurling. I know thats not the correct way to say it but didnt know another way.
