Thanks @yamanube for the pic. At the moment I feel pretty confident it's on there solid. I got new I rings and hd coupler from Jetmaniac in Daytona. I could use a washer under one lord mount now, but I didn't need one before. Thinking I just had the mounts in the other way last time and it was perfect. May swap those around and see if I get the fit I need it maybe it's just the difference in the head. Everything else is the same. Also the little difference in the acorn but on my girdle stud made a big difference in getting the pipe in there. Have to pull the box as well. Don't know if it's just an x jet thing or common. The x jet is lower by 1.5" if I remember right. And with a pipe this large that matters.
