The driveshaft is wrong, need to use a different yoke up front. May be able to locate one and then have your older one altered at machine shop.
That will save you a couple nickels.

Lots of misinformation found above.
For a 66' Mustang 289 car (I am stressing Mustang as I do not know the exact car we are talking about,) the factory C4 is the same length as the proper Mustang and common "short tail" Toploader with bellhousing. It uses the same 28 spline trannsmission yoke (assuming the toploader isn't the rare 31 spline model.) The driveshafts are also the same length too.
Also, the crossmember is identical and the toploader will use the same rubber tranny mount. No mods are needed here.
He can use either a factory shifter (not recommened for hard shifting) or a Hurst Competition Plus which will work in the same floorshift hole, even with a factory console.
The starter will be different as the manual starter has a different mounting flange than the automatic.
