Mine are shot. According to Progressive I need part # 30-5008 (set of 4 bushings) problem is they are unavailable from any supplier in Canada & Progressive wont ship by mail & can't give me Fedex shipping cost without ordering! I estimated on Fedex website to be around $75 U.S. plus brokerage

All U.S. suppliers show either out of stock or unavailable, shipping around $35.
Anyone ever change them with any other brand/homemade solution? Don't want to mortgage the house for a $20 part!
