Vibration dampeners

Okay, bit of a dilemma here:

Pulled brackets from a 98 2.5L to accompany my new power steering pump and alternator (and MPI system, I'll update my build thread later), but the pulleys don't line up with my vibration/harmonic dampener.

JY wont let me take the dampener too, and I'm finding out that 91+ (or something like that) 2.5L dampeners are dealer items... don't feel like paying 150+ for one!

Anyone know if the 4.0 dampener will work in place? I know I'm practically in foreign territory for everyone... but I guess it doesn't hurt to ask!

My plan for now is to get over to the junkyard to do a visual check, then take my spare dampener to the auto parts store to compare to a 4.0L one (my spare should actually be thicker if the 4.0 is correct). I'm just so short on time lately that I figure quickly asking might save me time...

Thanks for looking!

Did they have a 2.5 in 98???

DUH, never mind, I see it! LOL

It does not appear to be interchangeable, but I'm not sure what you will find with your physical comparison...

Okay well thanks alot, I'll definately consider buying from there once I do a comparison!

*back from death for information purposes*

It seems the vibration dampener from a 4.0 will work, I'll go pick one up and test fit it to my engine.

The only difference looks like the foreward lip has a heavier and thicker casting on the 4.0.

Also looks like anyone who wants to move their alternator right below the A/C compressor should use the brackets from either a; 2.5L, ZJ 4.0, or any TJ (possibly YJ too, don't have an example to look at) 4.0/2.5L. You'll just have to set up another electric fan!

Nothing ground breaking, but the water pump pulley from a ZJ 4.0 (probably wrangler too) is the right fit to a later 2.5.

I'll put all this in my build/conversion thread later, along with lots of pics!
