I am doing a refresher look for a Yblock to AOD kit, hoping that something new has come up in the past few years.  I emailed Wilcap, I received a reply from Speed Gems/Bendtsen's. Wilcap is currently being bought out by Bendtsen's.  Pretty much every vendor I have found selling Yblock to AOD kits are selling the Bendtsen's kit.  So, I would assume they are going to be the only source to mate a modern Ford automatic transmission to a Ford Y Block (other than Flat-O Product's C4 bellhousing).
