Happy holidays all! I would like to ask if the "old style" BDC coils ( photo below) will fit an Aspire Nautilus tank? I want to rebuild but the BVC coils are impossible to rebuild, for me anyway. As you all know, the BVC coils are also threaded on the top and the "old style coils" are not. Will the coils in photo still fit properly or were they designed for an older styled tank? Thank you for any help !
