Being on the lucky side I have a local parts store that is very good, I can 
wander behind the counter for the odd items. If it is not in the store they 
will have it in an hour most times. I also buy a lot from the local Ford 
dealer as he discounts me as much as possible, many times he is cheaper than 
the aftermarket stuff. Only use the chains for oil, wax & filters.
