Just bought a 63 willys cj5 with a dana 25. Promptly broke the left front spindle and I want to replace the old front end with a Dana 30. Is this a bolt on tranformation? Is there anyone out there refubishing dana 25s or 30s with the disk brake conversion? I would love to simply purchase a Dana 30 that has been refubished with new disks and bolt it on rather than try to rebuild one myself.
