I have a brand new Ford Super Duty stabilizer bar part number 8C2Z-5482-B - you’ll have to check the part number to see if it will work with your E250, E350, or conversion kit I believe it works for 2008+
I haven’t even taken it out of the shipping wrap because it was “lost in the mail” so I bought one from the local ford dealership and shipping it back it just too much!
$80 which is less than the dealership and just a bit more than a junk yard. If you wanted it shipped it’s $90 from UPS or $30ish from the USPS. I am willing to meet pretty much anywhere in Western Washington.
