1998 V70 T5 Heater core junction screw

[Conrad Birdie]

Not having come across specific information regarding the type of torx screw that retains the junction block with the two rigid aluminum pies into the back side of the heater core I am not sure if what was in there is original. The heater core itself was original though, dated from 1997 and the torx screw seemed to come out rather too readily and is the same type of sheet metal screw that, for example, retains the glove box or other parts of the heater core.It looks as though it would be a regular threaded bolt going into the metal block so I need to find out as the sheet screw simply turns and will not actually go into the block in order to fully seat the end of the tubes with the o rings into the base of the core. I managed to seat them somewhat but of course it is a tight fit so they will only go so far. Any help would be greatly appreciated!

Found the obvious answer shortly after posting after coming across an image showing a standard fine threaded screw, which made sense. i found a suitable one and got everything together.
