When it comes to heal/toe shifters, here's something important to remember. The movement in the heal/toe shift lever needs inspected every 8,000 miles, or sooner. When rocking outboard and inboard on the heal and toe ends, acceptable movement is less then 1/4". Anything greater means that the lever that includes the pivot bushing, and pivot pin needs inspected and probably replaced. Fortunately, Kury now makes a lever kit for replacement purposes.
Please note: I've not ordered one of those kits in yet to verify that the kit comes with the pivot pin and too.
