'Vim mapping for diffget | diffput not working with v:count

Pretty new to mappings in Vim,

In Diff Mode I've got C-Up and C-Down mapped to [c and ]c for diffjumping. I'm wanting to map C-Right and C-Left to :<C-U>diffput v:count<CR> and :<C-U>diffget v:count<CR> respectively to speed up merging.

nnoremap <C-Left> :<C-U>diffget v:count<CR>
nnoremap <C-Right> :<C-U>diffput v:count<CR>
nnoremap <C-Up> [c
nnoremap <C-Down> ]c

This should.... put from buffer # or get from buffer #.

But I get the error "no matching buffer for v:count".

the command looks to be taking v:count literally and running :diffget v:count instead of :diffget 3 for example.. how do I get v:count to resolve to a number? like dereference the variable?

I can echo "diffget v:count" and that looks to be correct... but obviously doesn't do anything...
