Would this 727 fit in my 1973 Duster?

the motorhome 73' 440-3 and 727 trans. fits nicely in my 67' barracuda. I have a later type K-member with spool motor mounts. The mid 70' trans. crossmember I got takes a dounut mount. Got the HeavyDuty one for a 73' ish 360 at parts store (Carcraft). The throttle cable, kickdown linkage and bracket need replacement. also need a custom length driveshaft. hope this helps, C300
