Are you talking from the hole underneath the bed cap? Or the front corners where the cover and the cover rail meet? I live in the desert so I'm mostly concerned with dust right now but I was looking at the fit both in the rear and in front and I see holes at both ends that I could stick my pinky thru.
Yep...I got an early MX4 as well. Install when okay without the shims...then I found the bulkhead spacer in the bottom of the box and no instructions. Not hard to figure out how to install, but it required I take the whole thing apart again and install the bulkhead spacer...Arrrrrrrg! I let Bak know I was unhappy to not have an addendum added to the installation directions. Also, found a ton of aluminum machining chips in the pickup box after the install....had to vacuum them out of the spray bed liner. Twice! Overall, a nice product and I am happy with cover as well as the bed extemder.

GeneUpdate: 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 rails and making a slight modification to the clamps.
the instructions for the Ranger states the importance of fitting the clamps as high as possible on the grooved surface of the rail. The clamps will not go up to the top groove so I removed just enough metal from the clamp to allow the clamp to fully engage the top grooves. This allowed a better fit of the bed side of the clamp onto the tiny metal lip of the bed. With the shims in place and the clamps fully engaged, the clamps stayed straight and tightened down properly and the seals along the top fit better. Here's a before and after comparision of the clamps. Not much material is removed, I tried the fit until the clamp would slide in the grooves.
Had mine installed today. My installer had a few issues but got it done. I think one of the prop roads may me on backwards.
Do you have a picture of the rubber cap on the end rails at the tailgate? Mine did not come with anything.

This mod increases the contact with the pinch weld flange and allows the clamps to fully engage with the rail. Works perfect. Clamps kept trying to flip out before. 1/16” is all it takes.
The groovei n the clamp for a reason. By not using the groove it may cause the clamp to slip in a vibratory environment. the clamp forces are not opposed, thus createng a moment which could exrbate the loosening.
The first rails were just raw, unfinished CNC cut aluminum ends which is probably what you have. These ones have that thin rubber bumper piece. Its enough to not gouge the tailgate but not sturdy against any sort of torsion
