welding milodon sump. Mig or Tig?

Hey Shags, had to go through a similar process mate. I have the same rack and pinion setup with a 5.7 Hemi. I ended up chopping 'x' amount out in order to get 10mm clearance between the top of the rack and the sump. Just be careful not to cut too much out as the crank sits quite low in the pan already.
