Now I have my mini stripped (nearly) ready for the blasters Ive noticed that the rear passenger floor pan looks like Giant Haystacks (if your old enough you know) has been jumping on it.

Whats the best way of putting it straight?
I was going to put a board and plank up against it then jack up the car.

Thanks

Side to side, front to back, or both? 

 

Put a flat board (chunk of worktop?) to it and try and work out if it's stretched and where. If it is you're only likely to turn it from an outty to an inny

You could always get Big Daddy to push it back up...hahah

 

The problem is stretch, across the floor the ribs open up a bit which tends to make it sag....difficult to get it back but as Ethel says its basically down to jacking it up, you can try on both sides of one rib at a time, length ways which may help.

 

I came to do an old rally car that had yumped so many times the centre tunnel was about 1/2 an inch down, jacked back up ok

Will try plan A and see if jacking it up on a block fixes it. If the outie gets converted to an innie I will have to work out how to shrink it.
First thought is to cut a strip down the length which would with be thickness of cutting disk or blade on reciprocal saw. Jack it up to close the gap then seam weld the length. Thoughts?

You'd have to be a very good welder. If it's stretched across the channels you might manage to take up the slack by tightening up their angles. It'd be a lot of work, but you could screw together a wooden former out of strips of ply on a board and make a chaser to tap along the channels.

Have you tried hitting it with a hammer and putting the carpet back down. Think that would be my approach
