89 Ovation track/suspension upgrade questions

I have an 89 ovation that I would like to upgrade to a larger track. I was thinking after reading a lot of other posts of using a 90-98 phazer 2 skid with a 121 by 15 by 1.25 track. My questions are;

Will this skid bolt right into place and are there any other skids to consider?

Any recommendations on upgrades to the suspension before install?

Are there any other modulations I need to make?

Any suggestions or exact parts are greatly appreciated!!

Thanks
