Will a reaar end, springs and driveshaft from a 70 Dart 2dr fit in a 66 2dr?

Hi All,

I came across a deal on a rebuilt 904, rebuilt 7 1/4 with 3.23's, nice springs/shackles and a driveshaft from a 1970 car pretty close to me. Will this fit in my 66 2dr dart? A bit of research is leading me to think it will but I want to check with the hive mind.
The torque converter won't unless your engine crankshaft is later than '67. You would either need to build a custom converter with the small snout, or change the front pump assembly on the transmission to the earlier style....like maybe off your old transmission? The driveshaft will depend on the wheel base of both vehicles, and the u-joint size (or use conversion u-joints)
