I tried at FSC, but nobody answered yet, and I'm not registered at GMFS. I called trailmaster and they gave me a phone number for some rocky mountain place that sells parts and has them drop shipped from trailmaster, but the parts are $60 each + shipping. I'm a cheap-a$$ and don't want to pay $120+ for two tie rod adjusting sleeves, so I'm trying to match them up with an OEM part. Trailmaster wouldn't give me any info on the size of the sleeves.
