We are in need of help repairing a sloppy steering gear box in a 1927 GMC T40 firetruck. We have identified it as a Ross gear box/column however I cannot find the specific gear box identification, i.e. part number/model/etc. I am not sure what other years/make/models used this same gear box. Any help would be appreciated.
Here's what I know:
1927 GMC T40B chassis 2 ton
Ross gear
