I gave up on RA after realizing that the shipping charges, estimated delivery times, and shipping locations were one big cluster and I wasn't really saving anything. Sure the parts prices are low, but to get it to you is roulette. Their website though is a great tool to get any idea of what's available. Get the part number and use the shopping function of google. Amazon, summit racing, and many others typically have the same parts slightly higher but in many cases free shipping.
