winch bumper and rocker guard questions

I got a REALLY good deal on a C4X4 bumper and couldnt pass it up cause the guy was comeing through town. He had it on a 1991 Cherokee and I have a 2000 Cherokee. I was wondering if there will be any mounting issues? and if so is there any kind of solution to the issue.

Also I bought Rock Rails off of the guy that came off of his Cherokee thats a 2dr and mine being a 4dr i was wondering if that changed anything?

Thank you in advance for all help.

The parts should work fine on your rig.

thanks man, i just read a little article about them and it said that an older model bumper give more clearance on the newer model ones.

exactly... when I ordered my bumper I got one for an older model for just that reason
