Trunk divider insulation

Installing the trunk divider with insulation, does the insulation go toward the trunk or the seat? I believe the trunk, but am not 100% sure, took it apart ten years ago and can’t really remember. My other two cars have no insulation so can’t compare. Thanks!!!

Discussed a few days ago: https://board.moparts.org/ubbthreads/ubbt...tml#Post2602823

Not sure how I missed that, but I’m working on a 3rd gen Charger SE that did have insulation, not an E-Body. I did search this question prior to posting and did not find an answer. So all that being said, can anyone help? Thanks!!

According to Detroit Muscle Technologies website

DMT Brand Rear seat trunk divider 3/8" shoddy material / sound deadener that can be glued to the front (facing the rear seat) of the trunk divider board with 3M spray adhesive

Thanks, I also located what is left of the old one. Obviously it is nothing like the repros it is all one piece board/insulation and the board part of it is more of a thick roofing felt type of a material and it actually extents out over the inner wheel wells behind the seat. Maybe there is some markings of the bracing on one side or the other.

What car are you referring to? I have pictures of an original 70 Challenger.

My 74 Charger has the thick roofing felt type material on the interior wheel wells (black), the lining of the sail panels and the roof (brown paper like covering). I'll post a photo showing the sail panel and the wheel well piece. Also photoof a template I made of sail panel insulation. I do not remember my divider having the insulation on the divider panel. I have another 74 Charger I'll look at this morning. I'll also post a better photo of the insulation on the wheel well. By the way, the templates worked great for the sail panel insulation board.

Thanks for the pictures. I'd be interested in one of your old sail panels. Never seen those.

original sail panels from a 70 Challenger

Here's a few more photos from my 74 Rallye Charger.
The first two show the composition of the old sail panel insulation board. They have a thick paper board on the back, a tar composition in the middle and a thin paper on the top and is fragile due to age. The 3rd photo shows the wheel well sound insulation on the wheel well that I believe was referred to in the original post about at the sides of the trunk divider board. It is about 0.125" thick, asphalt/tar paper composition and about 24" long and 3.5 inches wide. Also fragile, hence the duct tape holding it together It's put on wheel well with rope caulk. It's the first time this car is apart. I could not find any reproductions of these panels so I made my own and kept the templates I made from the originals. My panels I made from my templates fit perfectly (better than the sagging originals). My other Charger has the divider board and if I can, I'll remove the rear seat to see if it has insulation. It's right at 32 degrees out (car is outside) but I do want to answer the question asked as posted by 340Cpe.

I pulled the rear seat out of my other 74 Charger and the divider is not insulated and it does not have the insulation covering the wheel wells. I did find the broadcast sheet for a 73 WP Charger with M code engine under the seat though. I suspect the interior was changed out because it does not have the 74 seat front seat belts and it has a front bench seat with armrest. Sorry I could not help you 340Cpe. I will be insulating my trunk divider also and will be facing it toward the seat back.

Thanks for trying. I'm glad you posted the insulation on the wheel wells. My car is a 74 and is an SE which may make a difference. Those wheel well pieces and the trunk divider are all one piece with insulation on it. I do not know how to post a picture on here or I would post one. There is enough of it left to see. I also did a similar thing with my sail panel boards. I do not have enough of them left, I actually put them together like a puzzle and used that as a template. if you could supply Detroit Muscle Tech yours as templates it would be great, if you have not delt with them before they are GREAT people to deal with and genuinely want to help the hobby.

The sail panels are not insulation.

They help prevent holes being poked through the headliner material by covering the openings in the steel roof side frames in easy reach or rear seat passengers.

340cpe, I made a set of templates from my disintegrating sail panel boards. I still have the templates for my next Charger and they are dead on to the panels I pulled out. I'll post a photo of the ones I made from the templates which are now installed. Alaskan T/A, thanks for the info. I thought maybe the sail boards were for sound insulation because it reminds me of an old version of DynaMat. There are hard plastic panels which install over the crumbling sail boards and headliner and cover most of that area. Thank you for the info.
