I have been looking for something like this. I have 3/4ā gap on the front edge to the weather strip that came with cover. The problem with this particular one, is that they only sell large quantity and itās expensive. Right now everything in the bed is in a sealed bin.
I learned a long time ago about soundproofing stereo equipment. Every time I deal it with, I make sure all the hard pieces have something soft attached to eliminate rattles. Those rattles are like nails on a chalkboard to me. šµāš«
Installed these today to replace the āupgraded Alpineā speakers. Major improvement. I can hear the whole range of my music now. Clearer highs and improved mid-bass. The bad thing is now I want to upgrade all the speakers. $$$
For the front bracket on the roll bar; I chamfered the lower corner to clear gas filler bulge. I installed the Rough Country low profile hard trifold cover. For the cover; I drill into the roll bar base to get the front two brackets installed. Had to add extra weather strip on the front of the bed.
