65 Barracuda Heater Assembly

[pa340dart]

Will a 1971 Dart heater box fit in a 65 Barracuda
Found some contradiction out there as 69 and below will fit 70 up no go
Then again, 64-76 will interchange
Also what would be the differences
My 65 is a heater delete car and don’t too old for trial and error — might fit
Thanks

I believe the later heater assemblies - 67 and up - won’t fit due to the blower motor location and likely where the heater core fittings come through the firewall since the later firewalls are different than the 64-66s

Thanks
Now I’ll have something to go by
Tape measure is Easier than physically trying to fit it in there
Thank you again
