oldieoldie,

Did you by chance check this supplier (not mine):

https://www.chevsofthe40s.com/detail/6355/Chevrolet_Drag_Link_With_Rod_Ends.html

Although their listing says for 53-54, according to the MPL, this part number actually works for your 6400 (Utility) for years 1951-55.

After some further investigation, found the following information identifying "Interchange" manufacturer/part numbers that apply to the original GM# 3696469:

RareParts 25631
MOOG DS563
Affina DS563
TRW DS563
Spicer DS563

Further searching of these interchange numbers allowed me to locate several different supplier sources (besides the one above) primarily under the "Rare Parts# 25631"

I found at least 4 additional suppliers (none mine) offering that item, with prices ranging from as low as $60 to as high as $136 (not including shipping).

Example: https://ocpnw.com/nos-oem-drag-link-part-no-ds563/ (see Product Description that indicates "Rare Parts Interchange 25631")

The other suggestions to fabricate your own adjustable drag link will also fill the bill. Your call on which way you decide to go. thumbs_up

Good luck on your search!
