Idler arm too big ????

We are putting the steering back on the Duster and when I put the idler arm on I noticed that it was alot beefier than the one we took off. I thought hey thats ok bigger is better right ? Wrong !!!This thing hits my header on the right side. I double checked the part # K7086 which is the right # but I got this from Oreillys and they sold me their brand which is Master Pro . Has any one ever got one of these before and if so what did you do?
Is the Moog one any different ?
