R170 Ignition Tumbler Replacement

[bobs]

Hello, All. I've been lurking here a while but this is my first post.

I'm starting to experience the dreaded sticking ignition problem on my '04 Crossfire. (For those of you who don't already know, the Crossfire is a re-badged '00 SLK320 with funky body work) I already ordered a replacement unit from my Chrysler dealer but plan on doing the swap myself.

I found a whole bunch of articled dealing with the tumbler replacement, but nothing specific to the R170. So my question is this: Is replacing the tumbler on the SLK similar to the other procedures listed here or is it a completely different animal?

Thanks much,

Bob...
