You need thin 1/4" extension to get to the rear screw. To get to it stop the wipers in upright position. Then open the hood and remove the plastic plug on bottom of the windshield. The hole is smapp and normal size extension won't fit so you need the thin one. Sears carries it.

I've been told by a few of the chip companies that all the ECU's ending in 557 x and 558 x (x = any letter) are exchangeable. You just need to make sure it's set for tip or manual shift. I've had a chipped 558 M in place of my stock 557 P for 6 months now, and it works just fine. The chip manufacturer should be able to give you more info on this. As for finding your current number - it's really not a big deal to get the cover off to have a look. Really, it only takes a few minutes. It'll be good practice for when you get your chipped ECU!
