Transmission applications based on the numbers

Trying to help this guy out. Can the application be determined by these numbers? He has them listed on CL in Bowie, Md. He claims one is out of his brother's 69 Road runner but doesn't remember which one. I have posted this in the for sale section as well, but looking for info here.

Here is what he did give me from the pan rails:
The 1st 2 are cable shifted units.

F2464423 1332519

F2408004 0779713

PK2801542K 2392 9777 and found 2604 on what he calls the lower case, but have no clue what he means.

PK34106681 3035 2615 and 1764 on the lower case (again, whatever he means by that)
