in a 70 Coronet R/T....my car leaks so much power steering fluid out of this seal that it feels like I have to put as much oil in it as fuel in the tank.

I've got the column unbolted and pulled back, I've read the write up on FBBO forums, but I don't have a mini right angle pneumatic drill like the poster there used to put a few holes in it for drywall screws. This is a power brake car, and I'm not entirely opposed to pulling the brake master cylinder off, I'd rather not have to go thru the process of bleeding the brakes which otherwise work great.

any tips, suggestions, or advice?
