Only broke 2 drill bits.

Put a drop of oil on each before drilling, went easier than I thought.

Also, love these big -10 fittings. Been working with -6 for the fuel system past couple weeks and just got these -10 from summit.

Little closer each day to getting her off the jackstands.

Easier to drill if ya grind a flat spot on one side first.

Otherwise it can slip and then you can safety wire yer thumb to yer nose ring.....
