The 5.7 Hemi’s original steel (truck) oilpan had to be modified in order to fit between the Dart’s K-member and steering-centerlink.
I decided to cut up a bigblock Mopar oilpan and use the pan-rail of the Hemi-pan.
After a few tests I welded a small piece of angle iron between the pan-rail and pan-sump and started melting everything together. A friend of mine made sure the welds were good enough to not let any oil seep through and for good measure I decided to let a layer of solder seep in and onto the entire welded area the fully secure the pan.
