These links are front upper link for the RC10 according to Dirt Burners but they are only 1 inch long which seems rather short for RC10 front upper link. I gather it was to be used with special rod ends. I do combine shipping. Only $1.25USD shipping cost per additional items! Commit to buy the items through "Buy it Now" and request total before paying. Send me a message if you have problems with the cart. I will adjust the payment if you have problems while requesting an invoice. Thanks for your interest!
