OzyDuster74 full rebuild and hemi conversion!!

So we have commenced work to underside of car. Removed the petrol tank and will remove all brake and fuel lines. Tank actually in pretty good condition, looks to have a fair bit of rusty orange crap stuck to the walls inside. If can get a tank cheap will maybe replace. The straps are like new. No rust or anything found that raises any red flags. Excited to get it back to my shop and chassis stifen athen will raptor line entire under side of the car. Has anyone raptor lined under side of car thoughts?
Some one looks to have tried to sound deaden the underside with a poorly applied deadener.
