The proper acronym for knock on equipped Cobras/Shelby Cobras/AK's/COBs/COXs with the proper right and left side pin drive axles, installed on the proper side is "tight ass" or to define better...with an ear in the 12:00 o'clock position, wack that ear with the appropriate to you tool towards the rear of the car to tighten the knock-on. This would work for replica's/continuation and any other cobra type vehicles equipped as defined in the previous sentences. I hope I have this correct, but if I've misspoke I'm sure someone(s) will correct me.
