I don't mean to alarm you optimus1, but it seems highly likely that your Sunstreaker hands are from the
recent KO. The KO was packed with two right hands and no left. I've seen this a lot on Ebay lately whereby sellers use KO parts to sell a toy off as complete.
I only recently acquired Skids and I have to say that he is fast being one of my favourite G1 toys. Thankfully mine doesn't have the issue of the wheel sticking out from under the feet when in robot mode causing a slight imbalance. Highly recommended.
