I also believe this is for a 47-53. I have a 55.1 and the dash does not have a removable speaker and ashtray assembly. I know I just put in a new glove box liner last night. I also believe the 54 truck dash is set up the same as my 55.1. The ebay item doesn't appear to be cut out or made to replace a cut out area in a 54 or 55.1
That's my 2 cents,
Chris
