I'm really sorry, I just now noticed that I had a message. I've never had any on this site, and wasn't ever looking at the message box.
I don't know about the shoulder harness issue. I took the seats out of my truck and took them, along with the covers, to an upholsterer that I know. Sorry for the late response. I hope you got yours installed with good results.
Hi Perry, saw your post regarding your Clazzio covers. I just pulled my set out of the box and noticed there were no accommodations for the built in shoulder harness on the seat top on my covers. Assuming I was sent the wrong set, I emailed Clazzio. They replied I'd need to make a cut for this....no other instructions. to do this and get it around the belt it would seem you have to take some stuff apart. Did your covers come with an opening for that place? I tried Cover Kings already and they had a zippered slit up the corner so you could just wrap it around and zip them up. They sucked BTW....fit was so horrible I complained until they refunded me. Pretty sure they weren't the right set it was so far off. Anyway, before I start tearing stuff apart I figured it would be good to hear from someone who has already done it.
