is it possible to add a thin layer of dynamat sound proofing material before installation, will it all fit ok?

3 years ago

You can apply a thin layer of dynamat or like product onto metal surfaces prior to installation. However, don't apply material under rails where new acoustical panels will be installed as they may hinder proper fitment.

Where are the firewall pieces located in the cab and what is their purpose? Do they need to be glued into position?

2 years ago

The firewalls go vertically on front firewall (below front windshield). You have to remove cowl to install. Aprox 2" of the material is exposed and the remainder tucks behind cowl shroud.

Not sure which package to pick my serial number is SG 4-261000...

1 year ago

To determine which kit style you need, use the last 6 digits of your serial number. Your tractor cab s/n is 261000, so you would choose the option "After S/N: 185706".
