Jenn-Air 88370 drop-in stove, want to convert!

Question

I have an OLD Jenn-Air 88370 drop-in stove, likely the stove that was installed when home built... poor thing is falling apart, and the oven is too small to cook anything larger than a 9 lb turkey :) I have a new conventional electric stove that I want to replace with, however the Jenn-Air is hardwired (no outlet-- wired straight into wall) and the new one (obviously) has a 220 plug.

Any idea where to find a how-to on converting the hard wiring to a 220 3-prong outlet?

Thanks!
