Anyone know a part number and source for a replacement accelerator cable for a 2000 Blazer LS?

It seems that the end that is held by the pedal bracket broke off and we'll have to replace the cable.

While I'm on the subject, anyone know how difficult it is to replace this thing?
It doesn't seem very difficult if I can find a replacement.

edit:
I've ripped most of the old one out. I think I just need to knock the plug through the firewall and I'm done. Seems easy enough. I just need to find the right part now.

Thanks!

 

After some searching, it seems that the part number is 15010419 but there's at least two variants. So this is going to be a bit of trial and error to get the right part.
