Query: beware!

I double checked application chart several times,I checked the numbers when it arrived. All correct, I ordered the correct item and Amazon shipped that model.However, after several hours removing the existing air filter components I started building the new system. IT DOES NOT FIT THE THROTTLE BODY! Key cutouts are not there. Volant customer service is not open on Friday. So back it goes. Very disappointed. Will never buy a Volant product again.
