$200 I have a Wilcap Adapter (P/N 331-318AT) to put a Mopar 518/727/904 Automatic Transmission on an extended bellhousing 51-53 Chrysler "Hemi" V8. This is a new adapter that has never been mounted. Couple of scratches just from sitting around, but overall EXCELLENT shape. $200 Wilcap sells this adapter for $675 with a flexplate and a spacer. I only have the adapter, but Wilcap sells the flexplate for $175.00 and you could probably make the spacer yourself. Either way, if you buy this for $200, you're going to be money ahead of Wilcap's $675.00 package price. Instructions are available for download on their site.
