Re: heater core

If you are sure you got the right 3 screws removed, the cover can kind of get glued on after all the years of heat. I've had to pry pretty hard to get some off in the past.

Re: heater core

The ones on the box itself. I believe they are 7mm, iirc. There are 2 on the right side and one on the top, but this is going from memory and some pictures I found on this site.
