Changing out trunk pan

69 barracuda coupe.

Will level out the car on 4 jackstands shimmed to dead level.

I planned on changing out the transition pan first. Car also needs main floor pan which is rusty and also butchered up, and trunk pan both of which overlap, so i planned on cutting those pieces back at the transition pans overlapping seams to install the replacement transition pan.

Once thats buttoned up, i was thinking of temporary tack welding a piece of 2"×2" thinwall tubing across the framerails ahead of the spare tire well to hold everything straight. Then cutting the seams at the trunk drop off side since they got to be replaced too, remove the valance, remove the framerail tie bar, and slide the old trunk floor out from the back.

Was going to predrill alignment holes next to spotwelds i have to remove in tiebar to framerails for draw clecos to use as alignment pins to reassemble the tiebar.
