fatmat with stock insulation or not

[4aThrill]

I put in fatmat the other day everywhere through out the cab of the car, and just seeing if anyone else put the stock insulation back in there too or not, kick panels, firewall, heater box area?

i will be putting some kind of insulation in mine when the body and paint is done. not sure what kind i'll be going with hushmat dynamat ect... but i was planning on using the stock insulation on top also for extra sound deadening
