Thanks so much for everyone's response and excellent photos. My truck is going to also be a driver so I'm not going to get to no doubt go with the overlap that
I get the best possible fit. That hump in the plastic firewall cover is a stickler to deal with but I think all I can hope for is that I get it trimmed half way close.
I have read that those plastic push pins are a no go also.
Thanks again
Jeff
