Need help with part numbers for rear A/C lines

[reelop19]

I need to replace the 2 lines going to the back evaporator. These are the 2 lines running along the frame under the doors. I'm having a heck of a time determining which are the right one's using the parts diagram. Here is what I think it is:
19835A......6L2Z-19835-DA
19867A......6L2Z-19867-BA

Is that right?

or maybe 19835B and 19867B?
