Will this 8 1/4" work in place of my 7 1/4"?

"What difference does it make how much it costs? You need to have it done. No way will we have that info, since we all live in different areas and cost is different everywhere. "

It matters, do you like to know what something is going to cost before you do it? Maybe you don't, I do. I also realize the cost isn't fixed across the globe, but a ballpark guess is fine.

If I HAVE to have it done and cannot do it myself, no it does not matter how much. Since I have to have it done, it's GONNA get done.
