well i finally finished it lastnight! i decided that the tower had to go to hard to mount 3 taps to and was wobbly. (btw im going to be selling it for 100$ if any one is interested.) so after many trips to home depot and lowes im finished with the collar! here are some orginal freezer, before and after the up grade pics!
this was with the tower.
this is what the inside looked like notice all the rust!
finished product after the collar addition
fresh coat of paint on the inside!
