Looking for ROCKWELL TRANSFER CASE experts

I have a tractor called a M R S Mississippi Road Service--it is a 1965 with a 4-71 and 5 speed Spicer with a Rockwell transfer case. This case is a 2 speed--hi low and a front shaft that runs the front 4x4.



Rockwell model T 223 C1

SN 8 64 0004

Ratio 1 - 62

QUESTION I am trying to find what heavy duty truck used this EXACT transfer case. This is a component tractor made with parts that were out there at the time of build.

I have GOOGLED and called those big truck repair places all over the country. M R S has been out of business MANY years and the company that bought them out has NO idea about the tractor.



Maybe off of heavy duty Military trucks of the 60's , but not sure

Thanks for any help.
