I recieved this box as part of a package for a 1929 model a roadster I bought. guy said he thought it was corvair I did a search for corvair boxes and its difinately not one of those. theres no ford chevy dodge stamps on it. although from the part numbers I did find one has "FP" stamped above it ford part? but the Pitman arm has what looks like a GM vin number on it. any help is appreciated, couldnt find what I needed using the search button. Also if you know what this box is, is it typically used for cross steering or not?
