Need help wanted to know it the kenmore 80 series dryer with a 3 prong plug can be changed and wired for a 4 prong socket

Changing a kenmore 80 series from a 3 prong to a 4 prong

All you have to do is go to Lowe's or home depot and purchase a dryer pigtail about 25.00 and follow the bouncing ball, blk to blk, white to white, red to red and grn to grn... very simple. Time consuming
