I've been given a 1.2m Channel Master dish with mount, dish arms, lnb etc.

The lnb is a Norsat GM-6932 and is very old by the look of it. It also has the original feedhorn.

Is there anything I can buy so that I can use a black ultra lnb instead of what is on it at the moment?

I went further with the developing of LNB holder for Channel Master dishes. Now it is universal for 1m-1,2m-1,8m and 2,4m offset dishes and also any LNB (Ka, Ku, C-band) can be placed in the focus of the dish.

Sorry @Diavolo, somehow I missed your posts. There is collage I've made for 1.2m, 1.8m and 2.4m Channel Master antennas. Red digits represent all needed dimensions for 2.4m dish.

@tech1010 I do not have CM 2.4m yet, but have collected some information about it. The position of the focal point you can find in this collage, which I've made more or less universal for all CM dishes. Basically, the length of the feedarms could be very different, the main idea is that LNB becomes placed in the position that it's phase-center is co-located with the the focal point of the antenna.

if posssible pls share focal length details
Of course it is possible! But it depends on what you mean by the "focal length" ! Position of the focal point of the 2.4m CM antenna is 1651mm from the "G" point of the antenna.
Do you fully understand the collage I've attached to my previous message?
