I would have agreed with Mark completely, until a few days ago. My old diesel mechanic, who is retired on disability, is working off the price of an electric wheelchair that I tried to give him, but he wanted to pay me with his services so he is working it off. (Now, that is a screwed up sentence!)Mac, you can get all that at Walmart. As far as parts stores, it just depends on what their supplier sells. Most can get stuff in 5 gallon buckets, but I'd bet that walmart would be cheaper.
