Cab noise to loud!

[62 Barnfind]

I have been driving my 62 for two months now on the road. It rides really good and I have been real happy with the results except the noise. I went the cheap route and used the home peel and stick roofing insulation. Since I never drove the truck before the restoration I have nothing to compare the noise to. The cab noise is real loud. I know it will have noise but I have to raise my voice to talk to my wife. My exhaust is a 24 in glass pack dumped before the axle. I was thinking on adding a roof liner and door panel pads to help cut down the tin sound inside. I have look in the search and it seems like I have done what ever body else has done. Just looking for more suggestions to quiet it down a little more!
