Rockauto.com sells/sold the Lares products (note the incorrect unit/style).
Rockauto might ship yours to Lares, and then you know yours is correct for your year.
Lares shows an incorrect 1954 truck steering box - they told me that the four 1954 trucks/units that I had were all incorrect. They were, of course, wrong.
I sent mine to Lares via Rockauto. They came back in beautiful condition. Lares will return them in primer or in black.
Note: I did those in 2014
