2 X 31.00 = 62.00 Probably have S&H added on. Whole set costs 136.00 direct from Speed Pro. They throw in shipping at that price. Have you tried to contact them directly? Most of the suppliers that sold you the original can order two for you. If all else fails, call Speed Pro direct and find whether you can get two or just the whole set. 136.00 is not a big hit in the pocket book for a complete set. Another way to go.
