I have seen videos of floor replacement in 4 door cars, but I just got a 2 door hardtop.

Looking for guidance or suggestions from those who have done full floors previously.

Rockers are pretty much gone under rocker covers someone else stuck on there 30 years ago. I left remains of originals for the time being. Big sections of front floors were patched also. Almost to tunnel at drivers feet, less on passenger side.

My worry is that the original body mounts have shrunk so much that the cowl and rear of car are sitting lower on frame than they should be.

Just getting started, but so far it looks like all braces and mounts from floor front to front of back seat floor upright side-to-side interior brace are gone or marginal. Same with rear trunk brace. My trunk floor looks pretty good so far surprisingly. Have not removed gas tank yet, though.

Anyway, should know more tomorrow. Thought I would start this now so I can accumulate some feedback by the time the parts arrive and I have a better idea what braces are intact (or not) on body rear.

I ordered the full floor with braces, new poly body mounts and bolts, inner rockers, long rear trunk brace. I have lots of welding experience and patching floors, putting in partial pans, etc.

Did not order outer rockers yet, figuring on working from the inside out. Plus if I missed anything on prior order can add that also.

Anyway, my plan so far is to get the rear of the body firmed up with new poly body mounts and braces wherever needed.

Then use my pretty straight doors with renewed hinges (sloppy hinge pins right now) to line up quarter to the cowl which could lift a little with new poly mounts installed at the front, but maybe not cuz my tunnel is intact and some of rear floor is still there.. IDK..

But I should probably only be tacking the new full floor to anything until the door rears align with quarters?

I am not sure welding a lot of braces in now is a good idea cuz the rubber original body mounts on the cowl arepretty far gone and I suspect could have moved a little already. Bottom of door post seems to move a tad if I lift on door, at least on driver side.

The doors (even when lifted to remove pin slop) seem to be leaning down at the quarter and along window-to-top clearance too.

Which to me says either the cowl is higher or rear of body is lower than it should be already. So welding in a ton of bracing will lock them out of position.

I figure install all new mounts and braces where needed on rear of body rear and cowl to get body and cowl height re-established, then door rears to quarter before any bracing is welded in.

Then cut out tunnel and remaining floor to install the new floor that has braces on it already. New mounts on that also. Then just solid tacks initially. Then inner rockers, check and re-check door gaps, and worry about outer rockers when the alignment issues are satisfactory.

Right, wrong or somewhere in between? Will check back tomorrow with more info assuming no rain.

Thanks, Mike
