Should be able to find in Motors manual for your year, or chiltons/haynes. or try ford dealer service dept. they may copy a page out of their service manual for you. another resort is eBay under motors/parts, accessories/manuals...somewhere in these you should be able to get what your after
depends on how stringent the laws are in your state, and the individual who actually does the inspection..some are more lenient than others......can get a replacement from jc whitney for about 60/70$$
