Jim this is not what your going to want to hear but I'm saying it anyway.!! . . . . Don't bother and start again.

I say this with lots of experience helping folks who took the route your about to take only to regret it later. ONLY out come from taking this route is wasted money and time. Outcome is ALWAYS the same lots of work and still ending with under performing machine.

Honestly don't let others talk you into trying to improve it's false economy that never ends well.
