Flexy floor pans!

I never realized how bad the floorpans flex until Sunday!

Had the driver's seat out of my car to put the manual seat track on it (BTW if anyone cares...I weighed the power track from my seat, just the track, on a small hand scale I have that goes to 25 lbs and it maxed it out!)

Anyway put the seat back in and noticed that if I grabbed the upper seat belt holder thing, I could wiggle the seat back and forth (side to side), and it looked like it was moving at the bottom. I looked under the car while I pushed on the seatback and I could see the floorpan moving up and down where the rear seat bolt came through the floor.

Glad I have seat supports on those subframe connectors!

Yeah I've done that same thing with the seat and noticed the flexing floor pan.

Now you know why these cars are so bendy without SFC's. Just imagine in Eric's convertible, where the floor pans would be the only thing holding the front half to the rear half. Without the "Subframe connectors from hell" that are on it, the car would fold in half when you opened the doors :hick:

In all my years of experience with these cars, I have personally never had any problems with the floorpans...no flexing, no rust, no holes, no patching. And I'm in the snow belt. Plus I've been over 220 lbs. for my adult life. These cars have withstood everything I've ever put them to. I've always said that the floorpans were one of the only solid things about this chassis, at least for the Cougar/T-Bird.

As the years go on, and as more people chime in, it seems the floors aren't nearly as solid as I once thought. Of course, every car is different but still...time's catching up with us, I suppose.

I've never seen the floor rust out of one either, and I live in one of the rustiest places on earth (Thundergrowl would live in the other rustiest place on earth). Frames, rockers, fenders, quarters, doors, and even trunklids yes, but never a floor. Funny thing though - I've seen plenty of Mustangs, Fairmonts and LTD's with the floors rotted out.

Actually, check that - I did see one rotten floor. That '87 20th Cougar that still sits on that dealer lot (going on like 7 years now) had a rotten floor when I looked at it last, about four years ago. That was the owner's stupidity though - he parked the car in tall grass, close to the road (so road salt would be sprayed all over it in winter) and close to the harbour (so sea salt would be sprayed on it when road salt wasn't) and left it there all this time.
