Drive shaft install
So I got these great INTEGRY drive shafts- they have a set screw that holds the shaft onto the trans and axel stubs- all the videos I've seen the stubs have a hole through them where the set screw goes through- BUT my axel and trans stubs have no hole- can I just use set screws that will hold- OR do I have to drill some holes (with having a stroke- i'm pretty sure drilling may be out haha) ? or any other ideas? I am pretty sure this is a 90"s (?) style axial scorpion(?) no one has been able to ID it yet-
