I got mine from Repco, part No#SBJ 406 ARM. It's a silverline product. Cost me about $50 buck each but I doubt you will be able to get them at that price from them.
I purchased mine from Auto1 about a year ago. if you want I can see if they can still get them and work something out. I think they were about $70each. you are better to replace the whole are as if the pin is worn then the bush at the other end will be showing were
The part number for the whole lower control arm is BJ 406. Fits right or left. Google it or better try any site offering suspension parts. I bought one from the Repco internet sale for $ 4.06 ( yes $4.06 ) a couple of months back. Plenty around for $45 to $60 plus postage.
