Well unfortunately I've struck out on both counts.
I resorted to sending the old drag link to a 4x4 shop in hopes they could custom build a replacement, but no joy. I'm going to have them ship it back to me, maybe I'll try another 4x4 shop.
I haven't found a place that says they can build a Drag Link for a Class 8 truck. The OEM parts are long gone, there's no compatibility matrix that I've found.
The information I located was that the drag link p/n is 2388963, that number superseded by 2388955. The following alphanumeric code followed the part number in the parts book,#L-24-VU-405-A-11.
The truck is at a shop, the shop has exhausted all of its contacts and parts houses. I've sent inquiries to all of the northern ca salvage yards, and either got a polite no, or just no response.
I thought the upper mast jacket bearing p/n was 2455324 from

Any suggestions for creating a drag link and getting a one-off steering column bearing custom built?
