What @Dynosoar said. If ANYTHING looks different, other than that sensor on top of the transmission, then one or the other has not been properly represented. The internals of the parking brake are the same, so they can be swapped as well. from the cable to the lever the components are different.
Thank you both. I am sure the transmission is being correctly represented. The seller just wanted to be totally sure we had a match and was warning me there was a possible issue regarding the brake. I told them I would get on here and was sure the knowledge base would help with this. External parts difference are not a concern to me, so I am good to go with the 79. Thanks much.
