Insulation, t37 vs Lemans
Did the 71 T37 have less under carpet insulation than the lemans? Mine is pretty noisy on the highway and I noticed it just has a rug with nothing underneath, just bare floors
Also what about under-dash insulation? More in the Lemans? |

Yes, t-37 had less sound deadener and insulation than lemans, sport and GTO. They were build with minimal frills, extras as standard to lower cost

Did they have the firewall insulation? If not how hard is it to add it to my car?

'71 T-37 2 doors typically had no asphalt floor insulation from what I've examined. There is a sheet in the 71 Assembly Manual noting the deletion. Over the years i have ran across a few misbuilds with partial floor insulation in the very front. The '71 235 & 237 series LeMans floor pans definitely had the multiple piece floor insulation, same as '71 GTO. Once, you get to '72 models with the addition of the Lux LeMans 2 doors, they had an extra insulation panel. Firewall pads... On my HO T-37 Coupe, it has its original formed vinyl coated firewall insulation pad. The Coupe also has weight adding factory AC Going back decades, i've never disassembled a factory AC equipped '71 T-37 or GT-37 that didn't have that same formed firewall insulation pad. Will check my HO GT-37 on whether it has a firewall pad. I removed its dash many years ago to have remolded & am slowly getting back on it as a project. The GT-37 other than the drivetrain, is basically a strippo, heater vinyl flooring car.

Both the 71 T37s we have had only had floor mat’s and very minimal insulation. They both had power drum brakes, no AC, and were 350 2bbl cars.

I looked under the dash near the fuse box, looks like some kind of red plastic tile looking things lining the firewall, is that the insulation or did the PO put that in from the aftermarket?

Ol Pinion Head, thx for the info
Is the insulation on the firewall jute padding, what is meant by "formed vinyl coated" insulation? |

The black vinyl covering over the insulation.
Formed means its form fitting over the irregularities in the firewall

-The least expensive has been out for a long time. Maybe REM is the supplier/ cant remember. What many "builders" buy, as its cheap. -The more expensive molded reproduction was in the $160 cost range (have ordered one before), now close to $230. This more expensive vinyl coated firewall pad is not correct appearance wise either. -On an original, the molded rubber sheet has a texture to it. The original '70-72 A-body firewall pads I have carefully removed to reinstall, there is a raised "pimple" type texture face to the molded pad. Def noticeable once the inner heater box, fusebox, & complete dash are installed. Just throw the latter out as there are those of us that are beyond anal & this is an interior detail that is noted in Concours judging @ Nationals & @ MCACN.
