727 Trans

All passenger car 727's have the same overall length and crossmember mount configuration. Some trucks and vans have different tailshaft/tailstock lengths (always shorter). Many, many A-bodies are running BB motor conversions with standard passenger car 727's.... in my '69 Dart the top of the tunnel was tight to the bellhousing area, by on my '71 Demon it was not an issue. Pic of what you have, and/or the PK number at the drivers side pan rail may help further.
