Bushing is 1.25" tall. Rib is 1" tall--there's a 1/4" at the bottom of the bushing that has no rib.stainless steal dave said:walked out to shop to look at what is left of e-cliff's 60f. 1 plastic bushing broken up to much to measure. other bushing appears to have a rib on o.d. of bushing at very top and then missing the rest of the length of the bushing- been also damaged . is the o.d. of a new bushing round or is there a full rib about 1/16'' wide the full length of the bushing on the o.d.? this will determine time and cost to make them.......
