You should post more pictures of your alpha. I'm actually really anxious to be drilling holes in my frame but I want all the wires on the inside of the frame. The current access hole for internal cables is way to small for more than a brake line to fit through.
As you can see my wires just aren't going to fit in there very well. Also I need the shift cable going through that too so it only needs to be widened a bit.
Could anyone reccomend the best way of widening that hole just a bit. How tough is the material?
