If the parts store cannot get the part, simply thy another company. Often some companies are locked into using their own suppliers. When this happens and their supplies are sold out, then some parts get placed on back order. An alternate store might have additional suppliers to source their parts.

For example Porsche dealerships as a general rule can only order from their warehouse. We as an independant specialized store, can pull parts from many different warehouses across the US and Europe. We are even directly connected to OEM, aftermarket, and reproduction manufacturers so we can alleviate the "middleman" costs. This is where working with a specialized web site or a professional experience parts techician will aid you with your parts needs.

I would recommend no longer than 15 minutes. Montages that are longer than 15 minutes will often lose the attention from the audience especially in a party setting. Choose the best pictures and music that will fill the 15 minutes time limit and go from there.
