I have been working on my 1968 K20 Suburban before burbs were cool enough for vendors to stock parts for them.

To this day none of them are "the place" to go for burb parts. You will just have to shop each and every one of them for the part you need, and the origins of the parts from all vendors are all generally from the same manufacturer.

I have found over the years of shopping burb parts, that it's all about who has them in stock for immediate shipment.

On the steering gear, you may want to check your local Napa store for price. That way you will save on shipping. (Sending your core, and receiving your new part). If you don't have a core to ship, you will pay a lot more.
