Replace Product Model with SKU

Can Product text Model be replaced with text SKU in Version 1.3.5?
I'd rather have the nomenclature SKU appear in the place of Model everywhere. Any easy solution?

Tall order...go to admin>tools>developers tool kit
Enter "Model" in the first text box and in the drop-down select the first one in the list, then click search
and a long list of files where "model" shows up, you'll have to edit all of these files to change "model" to "sku"
Probably a good idea to print that page for reference to work off of, nice thing it will tell you the line #. Have fun.

I used to live in Navato back in the 80's. I was the general manager of the alvarado Inn for a while

Thanks Mike,
Your suggestion did the job. A lot of editing but the results came out perfect and error free.
