As long as you know the dimensions and have something to match up you should have no problem getting what you need. Look for other body styles and look at truck drums. Junk yards should be your best bet price wise but you might want to go to a different vender if you want new. Some guys can never find anything and others will bend over backward to make you happy. Find this latter guy and buy from him even if he is higher on some things. Smaller shops with employees that have been there a long time will be better at finding your parts. Chain stores that have younger employees are not bad just less experienced.
