CUCV Floor pan replacement problem

[pgp29646]

86 M1009 replacing the rockers and part of the floor pan due to rust. Ordered all the parts from LMC and most have worked out just fine (with small modifications). Problem I have is the "channel" (where the outer rocker sits near the door) of the front floor pan matching the channel of the rear floor pan. The front has a 1x1 inch "channel where the outer rocker sits. The rear floor pan has the same channel but it is only 1/2 deep x 1 inch. Also the bend in the channel is 90 degrees while the front channel has a more gradual bend. The rocker cannot sit into the channel on the rear floor pan. I do have the inner rocker panel and know there are modifications that will need to be made. Right now - I'm just trying to get the floor pans to fit together.

I only need 4-5 inches from the door of both panels so them not aligning in other areas is not a problem for me. How have others modified the rear floor pan to fit the front and allow for the outer rocker to sit in the channel?

Thanks!
