Gotta pull the pan. My Milodon pan hung below the K frame skid plate & a loose manhole cover split the entire front seam. Was scheduled to race on the flight deck of the Midway the following morning, so luckily, we found a guy to pull the pan, clean it with carb cleaner & acetone & he welded both seams. Bottomed out the pan on the bumpy freeways a few times after that & the pan held up. Glad I didn't try JB weld as was suggested by a few people!
