LMAO!!! while your method is surely faster...re-installing that puppy is going to be a serious venture...trying to get all those pieces to line up...and the glue you will need a tone of it!!! LOL
On the serious side...if you are using someplace like JUST DASHES, they charge quite a bit extra when there is no usable core.... they refurb the cores and that is what they market & sell, without a core they lose potential inventory, and the cost goes way up. just sayin
if you already have a replacement that is in good shape, then hack away! BUT remember things that are removed like that leave the re-install "instructions learned from removal a blank page" making it a much more difficult and time consuming task...again just sayin
