Start Up Rattle - Part Upgrade to Eliminate

[Seadweller]

Greetings!

My '98 base w/ Tip is going into the shop in a couple of weeks for some maintenance items, and while it's there, I was going to have an update I've read about installed that seems to eliminate the start up rattle issue.

I believe the part is updated from the original by the addition of some sort of spring that holds pressure on the tensioners. For some reason, I haven't been able to find it via search.

Could someone please let me know what parts I need for this upgrade, and is it truly compatible with my '98?

Has anyone done the upgrade and arrived at an acceptable outcome?

Thanks!
