OK good, so in that case he does need to find an H120 specific diff, not one fitted to any of the 1725 range

Eh?
The rear axles from any car in the entire Hunter/Arrow range will fit - the only difference is the ratio. The H120 uses a 3.89 ratio and so do lots of other cars in the Arrow range.
So he could use the axle from:
H120
or
Humber Sceptre saloon,
Fastback Alpine,
Hunter 1725 estate,
Hunter 1500,
Hunter saloon 1725 with optional overdrive.
All these use a 3.89 axle and the complete axle or just the diff unit be bolted right on to an H120.
There might be a few more - I don't have the parts book to hand.

Don't worry, I think I am just getting a bit confused!
I didn't realise the 3.89 diff was fitted to all those other models. The thing that threw me was the reference to the fastback alpine having the 3.89 diff, I assumed it would be the same as the rapier.
I have an axle that I took out of a fastback auto and I was trying to establish if it was suitable - I think I've got it now!

Ah - gotcha 
Auto Rapier has a 3.7 (and that was used on a few different models too  ).
If it was my car I'd be tempted to fit a 3.7 and get the speedometer recalibrated - it'll be better for motorway cruising.

Cheers for all the info guys. Not decided what I am doing yet, keeping my eye out for an axle but might try get my diff out and recalibrated.

Hmm, interesting. That might be something I consider for mine then, shame I've just spent umpteen hours stripping my axle back to bare metal and painting it 
I also have the speedo from the auto so could I do a straight swap??

My part's books lists the same speedo for auto and manual.
Hmmm - to be honest I've no idea!

H120 Diff Needed
