silverstude Posted October 31, 2022 Report Share Posted October 31, 2022 Does this look like one? It's in a 63. Link to comment Share on other sites More sharing options...
Avanti83 Posted October 31, 2022 Report Share Posted October 31, 2022 If the width is correct the only other dimension would be axle housing diameter. The 9" may be larger in diameter but that will just require a few modified parts. Shouldn't be a big deal. Link to comment Share on other sites More sharing options...
John D Posted October 31, 2022 Report Share Posted October 31, 2022 58 inch may be flange width, iirc stude is 58.5 lug surface to lug surface. Double check that Link to comment Share on other sites More sharing options...
CaleBitz23 Posted November 11, 2022 Author Report Share Posted November 11, 2022 Yes it looks the same, also it says it is 53" flange to flange but 58" hub to hub for the Ford 9inch I'm looking at getting Link to comment Share on other sites More sharing options...
