this makes me glad I decided on metra 80 vs. gila, but I'm sure you'll work it out. I got a tiny hole like that way back when I ported my first maxi in like 98 or 99. I didn't have any idea about timing or anything, but it ran hard for a little while. That hole was sorta a mystery to me until now because it looks like it coulda been machined, but thanks for clearing that up dood. Best of luck.
