Update: I managed to install my cover with one hand. I removed all the shims from the rails and completed the installation. I didn't like the fit of the rail top seals to bed trim nor the clamp fitment.
got the use of both hands and reinstalled the rails after adding the shims back to the...
i noticed the waviness in my windshield today.
It can only be seen when viewing across the glass from the side.
EDIT####
I went out to the carport to attempt a photo and I can no longer see it!
Could it be heat and the Sound Glass?
I'll keep looking cause I know I saw it earlier this afternoon.
Thanks for all the info and pics.
I have a BAKFlipMX4 ordered and my Ranger in the carport.
Now to just get the doctor to remove the wrist brace so I can get on with my install!
Appointment on the 28th......
