[align:right][/align] I'm finally working on Dynamat installation in my factory floor pan '68. I laid the Trim Parts rear carpet section on the Dynamat covered floor pan and I'm concerned about how baggy the tunnel is. I played around with repop sound deadener pieces under the seats and the rear foot box but only made the tunnel fit worse. I'd actually like to use some Dynaliner on the trans tunnel and front floor pans to cut down cabin heat.
