Hi Fred.
I have not got a definite answer for you , but I am sure somebody on this forum will have.
There are a few issues that might come into play , and I am open to correction .
Here are the issues I can think of : The later model engines are fitted at an angle, and this might affect the fitting of later gearboxes because of the bellhousing.I fitted a synchro box to my 1960 Ser 3 and 1725cc engine straight out - I think both came out of a Humber sceptre- with no problems, but the Hunter is a later model and the engine lies at an angle as far as I know.
Also there are different clutch and pressure plate combinations , 71/2 and 8" , and different splines ( fine splines 25 and 11 spline if I remember right )Seeing that you are fitting a better box you may as well fit the best of everything, which I can't accurately help you with but I am sure there are guys on this forum that have the knowledge.
Cheers,
Jan.

I have a series 3a rapier a Hillman Hunter GT gearbox a Laycock Denorman OD & would like to put this combination together in the rapier could someone let me know if this will work I have not got the extended mainshaft & will have to make one, perhaps someone has one. I want to do a complete O/H of the unit before removing old box as I will continue driving the car & not have it of the road for to long Reguards Fred
