They have a web site, but it's pretty much just their phone number. Order a catalog, they have a lot of stuff. Everything I have ordered from them has showed up within a few days, and they have good service. For example, I bought a timing chain set and a gasket set for it. I also ordered a water pump gasket. Well the timing chain gasket set includes the water pump gasket - the guy on the phone noticed that, and refunded me $2 or whatever the water pump gasket would have cost. One time they did have what I wanted in stock, so they offered free shipping if I didn't mind waiting. I got the part in 5 days. Excellent vendor, and they have knowledgeable buick guys because sometimes you don't know what the heck a part is called that you need.
For restoration parts, Poston and Kirban have about all the same stuff. For about the same price. Actually I was ordering heater hoses from Postons and I couldn't find the picture of what I wanted in their catalog but I knew where it was in the Kirban catalog, so they pulled out the Kirban catalog. You could likely pick out what you want in either catalog and both places will have it.
