Default C3 under-body insulation

I somewhat recently purchased a 1969 Corvette L-71 coupe shod with a factory 427/435 hp Tri-Power engine with factory side-pipes. Today I had a look underneath and there appears to be some sort of insulation setup on the underside of the floor. Thus, my questions are:

1. Was there any type of stock/factory insulation on the underside of the floorboards in the transmission tunnel area?

2. Was there any type of stock/factory insulation on the underside of the floorboards on a 1969 Corvette?

Yes, there most definitely was stock/factory insulation... Transmission tunnel, fire wall, which also wraps under toward the floorboards. I replaced all of it on my 68 (which was near all disintegrated) and is readily available from most all parts vendors. I believe I purchased mine at Willcox.

I think that I need to be more specific in my question.

I know that there is under-carpet insulation ... but was there any type of insulation on the bottom side (the road side) of the floorboards?

Hi John,
There were also insulation blankets on the frame rail side of both side-exhaust mufflers.
If your car doesn't have these that could be adding heat to your hot feet.
Regards,
Alan
