1969 Floor Insulation

[Steve M.]

I have a 69 350/350 with original side exhaust. My question concerns insulation under the splash shields under the floor and firewall. I have the phosphite metal splash shields under the floor and white plastic shields where the floor turns up. The white shields have the correct part number on each one. My question, was there insulation between the splash shields and the body? There is no evidence of clips/mastic or glue?
Thanks for any information.

Re: 1969 Floor Insulation

Yes, insulation was originally installed above the floorboard and toe shields. I believe the factory used a 1-piece insulation that was likely mounted to the body before the transmission was installed. There should be some little fingers on the floor board that grip and hold the insulation in place. Reproduction insulation is sold in 2 pieces for easier installation above the transmission tunnel.

Re: 1969 Floor Insulation

The insulation Jeff refers to was only on some 1069 Corvettes -- not all of them. If you can figure out which cars, or what options drove the instal of that insulation please share with all of us.

Terry, you continue to amaze me, please elaborate. Are you saying some did not have insulation, or some had different insulation? Option configuration might determine insulation or type?
For what it's worth, I've had 2 69s, January and April builds, both BB, both manual, both with insulation.

Re: 1969 Floor Insulation

FYI, my 69 BB side exhaust manual coupe (April 7th build) has manganese phosphate (Parkerized) floor shields and white plastic firewall shields. There is/was insualtion under both, held in place by riveted tabs (very sharp dual points that pierce the insulation and were bent over) in various locations in the transmission tunnel and lower firewall.

Re: 1969 Floor Insulation

I restored a 69 L-89 under car exhaust Coupe Serial # 4427 (I'll never forget that serial #). It was an early car (concidering they almost made 40,000). It had the under body insulation. Now thats the only early 69 I did (I have done dozens of late cars and none of them had it) and I always thought that it was the early cars that had the insulation. Now from what I am reading it sounds like they were spread truought he year?? Interesting. I still have copies of the tank sticker and dont remember seeing anything about insulation being an option.

Dennis is correct the retaining tabs for the foil insulation were the same as the ones for the trans tunnel insulation.

Jeff,
Gee, I thought I was clear -- but I'll try again.

Not all 1969s had the underbody insulation, and not all had the plates that run from the toe panel shields (plastic or metal) to the middle cross member.

I seem to remember a TSB instructing dealers to install those items, and their attaching hardware if owners complained about heat in the interior.

I'm sorry that I posted, it won't happen again.

Aw, come on, If I wasn't clear -- I'm sorry.

I did try again.

Re: 1969 Floor Insulation

Jeff,

I agree about the remark. With regard to the insulation. I also have the insulating pannels under my 69 350/350 with the hood insulation also.

Re: 1969 Floor Insulation

My early '69 (October '68) has insulation under both the plastic and metal shields. All is held on by those sharp bending retainers. Terry- if I'm not mistaken, the TSB was aimed at '68s that had no insulation. By '69 I believe that the factory installed it, as you said, on some but not all cars. If you have the fasteners or the remains of some anyplace other than in the transmission tunnel, your car had the insulation. The metal shields and tunnel insulation is detailed on J85, UPC 1 page B6 and the plastic splash shield is shown on page D9 of the same section with no mention of insulation.

Re: 1969 Floor Insulation

FWIW, my late '69 L88 side pipe car did not have the insulation between the sheilds and the floor boards. No evidence of clips or any other mounting or remains of old insulation, either. The car was very original, so I'm fairly certain it was never there.

Re: 1969 Floor Insulation

My late (last day) 69 also had no evidence of insulation. But did have the White plastic Dust shields which were suppossedly changed to Gray Phosphate metal by then.

Re: 1969 Floor Insulation

My November '69 L68 N14 car has only the white plastic toe panels (not metal as the TIM&JG says) and no floor panels or insulation (as the TIM&JG says it should have. No sign of holes or clips that it used to have them. It does have insulation over the trans. in the tunnel, but that's it.

Re: 1969 Floor Insulation

Thanks for the replies. My car is an October 1, 1969 build date and is exactly the same as the last response from Jamie.
