Can I use a C-band dish to get the Sat 105 ?

[China Doll]

I have a 9 foot spun alum dish, if I can use this, can anyone advise me how I should mount the fss lnb? also, the dish has one center arm where the C-band lnb was mounted, there was no ku on this dish.
I already have the lnb to get the 105 sat that has my locals on it, I had a superdish and a tree fell on it, I thought maybe I could use the big dish for 105 since I have a dish 500 for the other sats and just needed some idea as to where I should mount the lnb on the center arm of the c-band dish. It is the lnb that comes with the Superdish 105 setup, I have just
eliminated the other 2 lnbs and am using only the fss lnb. this is the same one that was on the superdish that I had that the tree fell on

Thanks In Advance for help
