I'm fixin to put my heater box in this week. (maybe) So, anyone remember what goes in these holes? I seem to remember maybe plastic pushins? I just don't want to have to yank it once it's in to put something else on there! I'm not using the volvo heater valve.

Also, if you are wondering here is a teaser! I'm not ready to post a for real update, but things are really happening! (that piece is not bolted on, just hanging there! But damn it, if I can find a pulley I like it's getting locked down!)
