Personally I would use the two 318 torsion bars you have. That way if you still have issues you wont waste a 340 torsion bar in the process to fix the issues. What is the original torsion bar number stamped on the end and what is the 318 torsion bar stamped? I will see if I can locate the one you need on the salvage circut that would be close to you. I will be going out to the salvage yard and I can look up everything that is currently out there with nothing blocked on their computer. What we can look up doesn't contain all the parts that are out there because many companies don't release their inventory on line. Of course they are a lot of parts that aren't on the circut either.
