Hello,

Take a look at the 15-111 pivot shoe, which uses either the 1/2" Series 160 or 3/8" Series 165 coil springs. The 15-111 is compatible with both sizes, so you'll have to measure your spring to verify the better option. Once you determine  the correct series, the compatible covers can be found under the related item section of our product page. Thanks for posting!
