Question about my intake.

[DRIVEN]

Pic 1 was for early alternator bracket. Pic 2 I can't tell.
Pic 3 was for early points style coil bracket. 1 & 3 are good to go. #2 may be for a temp sender but is likely a blind hole for a bracket. If you dribble some water in it does it hold or leak out the bottom?

I think #2 is an alternator bracket mount hole. Shouldn't leak any fluid.

Thanks a lot for the info guys, I appreciate it. I did a bit more investigating and just like you guys said, the holes are there for mounting various accessories and do not require to be plugged.
