wheel studs have a look
I just converted my 62 Savoy from left to right studs. The ones the book called for were wrong, period, wrong. I took my old stud down and we found a match, and they have knurl all the way across the mounting area as the factory style. Most are knurled like the one you show, but the right ones are out there. Unfortunately I didn't get a box with them or I could give you the part number. I found a couple that were very close, and the one you have looks like one of them. They went in easy. When I found the proper fit, I had to shorten them (lugnut on to proper length and zip disc the excess, screw the nut off to clean threads) but I feel 100% confident I won't have a spinning stud on the side of the road!
