Anyone have any luck with SEI's gimbal bearing and bellows kits? I'll probably end up using Merc, but I'm wondering if anyone had had any luck with any aftermarket brands. Any recommendations are appreciated. Application is an Alpha One Gen II (1997).

Do yourself a favor and buy merc rubber .Far better..Aftermarket may look like a slinky next year(questionable rubber) On the gimbal bearing .Link belt ,is link belt

So far SEI has done everything better than merc and cheaper....I wouldn't be scared.
