Sed character number specification
I have the following sed command:

sed '/7361105/s/^\(................................................................................................. .............................................................................\)....\(.*\)/\16776\2/' arch.txt > arch.tmp && mv arch.tmp arch.txt

and I would like to replace the n "." (174 characters) in the first expression, to an expression that does the same (indicate that I want to replace from character number 175).
I've checked it out in manuals and tutorials but I can't seem to make it work.
Any ideas?
