Hey eveyone, I bought a Thule crossbar set for my 2019 wrx. The company I purchased it from has a different set of part numbers to the Thule brand itself and screwed up my order. So long story short I have one crossbar and they won’t send me the other one until I know if it’s the front or the back. I put it up and it looks exact to the rear fixed points but I also see that it extends. I’m not sure how they are supposed to fit. So anyone with any info on this would be helpful.
