Do you reckon those sheets are the same as Dynamat ? I've got some left over mats I used on my yellow van , 10 sheets of 10mm x 500x300 which will be used in my mk1.
Silly question, are you putting the cards back on the floor so the back seat humans have a nice flat floor , if you need measurements I can check on our rally pack

Edit.. Urchfab on yt just bought a Midnight 4dr Escort, turbo Pinto, just a short vid...

So if anyone is on the fence around using the foil tape I would say do it, it was 20 bucks for two rolls and it elevates the quality of the finished job significantly I think. Shame it's going to be covered in underlay and carpet . 


 
Also I'm glad I decided to do the channels on each side, because it meant I had my face at a different angle and I spotted this little pile of grinding debris that had decided to start rusting.


 
It was under the back seat rail right in the corner completely out of site unless you were down low. Had to break out a pick tool and a tiny wire brush to clear it out. Then I stuffed a rag soaked in rust buster in there for good measure.
 

 
I've since gotten it completely clean and sprayed a bit of etch primer in there to seal any scratches up. Would have been a prick of a spot to fix if that rust had taken hold.
 
I'm having a break and some lunch then itll be back out to tackle the rear wheel arches.

Mark. So long since I've seen a std MK2, are those cross braces standard? Yes a thin sheet of aluminium is the go imo.
 
I reckon I would only line areas which will be covered by carpet?

Maybe... But years of build play a part over Aus del. Aus Escort was a flat pack and assembled in NSW? That's why your RS had a plug for the fuel cap , only Aus has the dropped tank.
Somewhere in 77 the shell started to install those braces , my 76 doesn't have them which came in handy for carrying 3m lengths of pipe . It maybe also cause a majority of cars came with a Pinto that has almost double the torque over a Kent, could also be safety strengthening, buckled roads etc etc? UK Escorts were basic in shell strength , they dittn have the body plating strengthening ours have as standard unless theirs was a Mexico or higher. I will accept corrections as I'm only going from my own experience, not www images which we know are very vague...

Part time, with the deadening sheets, and sheeting the gap , I can't see a problem doing that however I suggest to put slight X folds to 1, strengthen the area and 2, stop that dreaded drumming vibes . Lining the boot, you've got all that plank and carpet yeah, if you change your mind it'll be a pain in the arch to remove so don't do it.. Just my thoughts

Great job Mark.
 
You need a van Marty if you plan on carrying stuff.
You could be the cool guy at Bunning carpark if you had one.
