Is this possible? Going with a one piece would be nice, but can you get it in there with the quarters on?

Yes it can be installed with the quarters on. There are a couple ways to install them. Are you against removing the tail panel?

I would rather not remove anything which is why I had been looking at the 2-piece, but using a 1-piece would sure be nice.

I did it with my Demon.
1 pc. nothing else removed.

I don't recall who posted about it & FWIW I was highly skeptical but after looking it over I think it may be possible to slide the new trunk floor in from below the tail light panel & over the rear frame member... You would need to remove the complete old trunk including the lip that folds up & mates with the tail light panel, clean the frame rails & the flanges that mate to the trunk extensions & wheel houses...

Can't go in through the trunk opening.

I've seen guys either cut the taillight panel out or cut a slot behind where the bumper goes. (kinda hard to describe, but it slides right in.)

Honestly if your doing that much cutting and welding how hard is it gonna be to do a two piece and weld up the seam in the center? The gas tank hides it underneath anyway.

i saw a post some time ago where a guy removed most of the rear frame member and slid it in that way,that way you get the wrapping up over the taillight panel ,as it is original style.i think he cut the rear frame member on the outside of the fjäderhänkena(rear sprin mounts)behind the bumper.there was pictures to,look for it though i think it was on a E-body.

I put one in from the bottom......frame rails were out tho.....Copchaser from above will recognize this......

Sounds like a lot of trouble for just a little more welding so as was stated, I'll just go with a 2-piece. Thanks guys.

Support the heck out of everything. I know a guy that got his Falcon convertible back from the shop with a sag so bad the doors wouldn't open without a fight.

2 peices are the way to go if your not cutting the 1/4's or the tail panel off
