He didn't drill anything. I never really looked at the thing to see how it was attached, but it took him most of a day to figure it out. The bolts may be down in the threaded holes??? May also be closer the the center. The bolts are there, ya just got to find em. Dad kept calling me to come help work on the thing but I didn't want to spend a weekend working on a wrong wheel drive, plus the car is a real piece of crap and he was just getting it running as a favor to my aunt. Guess I should have helped, then I could help you out better.
Maybe try to find a 3.3 out of a car in a junkyard to try and find the bolts easier. I know these engines aren't real common, but they are out there. Or look at a new balancer at a parts store.
I'll go talk to my dad tonight and find out exactly how to remove it.
Sorry I can't be more help right now.
