this is an INCOMPLETE kit for the 93-97 lt1 equipped f body cars. Missing are hardware, rubber couplers, 90 degree intake elbow. All I have is what is pictured. Might need estimated 100-150 dollars to be ready to go. The bd11a head unit is vented and spins freely bearings are tight not wobble. I will only ship in the US shipping is set at $60 please do some research to make sure this is what you are looking for once again the kit is NOT COMPLETE
