I'm having a hard time figuring out what I need here. My front spring seat on the driver side has completely worn through and fallen out, so when I replaced the strut recently, I didn't even think to check if a piece was supposed to go there. Naturally I have some nice new noises when I turn the wheel. Here's the strut https://www.carid.com/monroe/oespectrum-front-left-strut-mpn-71484.html?singleid=17928597 and you can kind of see that it has a little tab sticking up along the spring seat. The lower tip of the coil spring presses against that tab. I was thinking the insulator should be a semi-circle in order to have space for the tab, but the insulators that come up from a specific search don't seem to have it, they're full circles. https://shop.advanceautoparts.com/p...ring-seat-insulator-l5013845224feq/11586258-P What needs to go in there exactly? I'm broke af, so the cheaper the better, universal, etc. I've even heard of using duct tape, but I can scrape up a few bucks, no need to stoop to that level unless it really is a tried and true method. If universal is the way to go, anybody know what the diameter should be?
