The good news is you'll have an easier time with it since your truck is 2wd, no messing with the transfer case. What parts you'll need depends on the AX15 that is available and if it is the internal or external slave cylinder and if not do you want to swap it to one, etc. There's plenty of info on it on Google as it has been done many times. If you can find out the year of the AX15 then you can get an idea what you'll need, again depending on if you care about the slave cylinder or just getting your truck fixed. Of course if you're going to do the swap it's always preferable to have the external slave for obvious reasons.
Now about that Peugeot, the one good thing I will say about them is that they are so universally hated you can pick up another one on the cheap. People are only too happy to get rid of them. If you can't find any locally, they are small and light enough that you can have one shipped for a reasonable cost. That opens up a lot of sources. I've seen them on Fleabay for under 200 and that included shipping. I throw this info out there just in case you don't wind up with an AX15 for whatever reason. I wouldn't try to talk anyone into keeping the puke goat. If I did have one on my vehicle and I was going to keep it that way, as long as I had a place to keep them, I'd keep a couple spares on hand.
