69 L78 radiator question

[70lt1z28]

i have a 69 L78 4 speed car with a straight neck radiator. I believe the radiator is a 3 row. the core (with out tanks) measures 23" across by 1 3/4 " in width.  the tanks are original with the original tags and date. of course at some time the core was replaced. my questions are
                       1) is  a 3 row core correct?
                       2) are the measurements correct?

       what i am getting at is: I want to have the original style top and bottom channels installed on the core and I want to do it the right the first time. 

                        1) anyone know where to buy the channels?
                        2) how about a good radiator shop to do the job?

                                                                             THANKS IN ADVANCE
