PST 1.03 TORSION BARS

Hello Mopar brethren I need some advise, I purchased a set of pst 1.03 bars from James on his ebay store and they arrived last week. I started fitting them up tonight and the drivers side went in with out any issues where as the passenger side fell in place just as the other side but wouldn't go in any further to fit up the clip.
I removed the bar and fitted my old one in to make sure it wasn't any thing up front causing any issues bar went in no problems so I measured the 2 bars and found the new bar to be 3mm longer in length. I sent James a msg tonight and will wait on his response to see where we go from here but can you take some material off the face side of it with out causing any structural damage to the bar as to sending this bar back for a replacement will cost a small fortune from Australia.
