Re: Floor pan
I'm at work right now but I have more pictures on my home computer of how I did my full floor with inner rockers.
To quote an older saying. I'm not an expert but I did stay at a Comfort Inn last night.
If BlueSS454 or pretty much anyone else has other suggestions I would listen to them over my suggestions or procedures.
BlueSS454's work is absolutely amazing and we are lucky to have him as a resource.
The floor I used was a Dynacorn with braces, inner rockers, and seat mounts.
Think about how you are going to weld everything back together. Spot welder? Plug weld?
How are you going to remove the floor? Itís spot welded to the trunk floor, package tray braces, under the rear side window area, rockers on top and under the car, firewall, toe boards, and cowls.
Get your holes punched for plug welds before you put the new floor in the car if you are going to plug weld.
Are you replacing the cowl or parts of the cowl on one or both sides?
This is the abbreviated version of what I did.
I replaced all the body bushings with new poly bushings and got the body aligned on the frame.
I tacked some small bolts at 4 corners of the body and dropped a plumb bob from the bolts to the garage floor and marked the floor so I could get the body back aligned to the frame.
My frame was sitting on cribbing and the wheels were blocked on the cribbing so the frame was not going to move.
Braced the body inside the cab and across the door openings. I might have over killed this a littleÖok a lot.
Got the old floor out. For me I drilled all the spot welds out with a spot weld cutter or more correctly several spot weld cutters. There are a lot of spot welds so this takes a while.
Once I had the spot welds out the floor didnít really show any signs of wanting to come out so I cut it into two pieces and then it came out pretty easy.
I did some selective replacement of the cowl areas and replaced my outer rockers.
I lifted the body up off the frame far enough to get the new floor between the body and the frame.
I temporarily attached the floor to the body with a few sheet metal screws and held it in place with a couple of small ratchet straps.
I lowered the body on the frame.
Removed my temp floor attachments.
Moved the body and floor around until I got the body bushings back in place at all locations on the floor and body.
Made sure the body center line was matched up with the center line of the frame east and west using a string line attached to the frame and marks I made on the body before I took it off the frame.
Used the small bolts and marks on the garage floor where I dropped a plumb bob to get the alignment of the body on the frame back to where it was.
Did some double checking of all the measurements. I wanted to make sure I was in the ball park with the floor alignment and the body was square with the frame.
Snugged up the body bolts.
Put some sheet metal screws in to hold the floor in place while I welded.
Welded the floor.
Obviously this took quite a while and I was checking everything at least 4 times before I called it good.
Is it perfect? Absolutely not!
Is it up to the quality of BlueSS454? Not even in the same country as the ballpark BlueSS454 is in.
That being said Iím not unhappy with the results.
I had fun figuring out how to do it then getting it done.
I've had the body off the frame several time since the floor replacement and everything seems to be good.
Got a little weld cleanup to do yet but that is minor.
Not sure this helps you any.
