The C-band Norsat needs a WR75 flanged feed horn.
You need something like a Chaparral feed horn (www.chaparral.net) or similar to mate to the LNB.
However, the fit of these depends on what dish you are using. The Chaparral feedhorns are primarily intended for (prime-focus) dishes with an f/D of about 0.3-0.4, whereas most offset dishes are 0.5 and higher.
Prodeling and Skyware Global makes feedhorns for WR-75, for example http://www.skywareglobal.com/images/pdf/C-band_RxO_Feed.pdf

TBH I don't know, it came from the top of my head.
You are of course right, the interface is a WR(CPR)229.
The Chaparral and the Skyware are WR229 ones.

Post some pictures of your stuff and, maybe then, some ideas will be generated.
Add: Or try Google "LNB for offset dish", you will get lots of examples

You probably either need something like this:

or couple something like this

with this
