You can get the dash bar under the dash and still have functioning wipers. My cars front tubes were ran under the inner fender well thru a hole in it tied to the frame. Not the best pictures, sorry.
That looks really good! I was planning on doing it the same way as you from the firewall forward but the Turbo's, plumbing etc are in the way. I may tie it onto the side of the frame rail in the fender well instead. Need to ask my buddy about it, he knows the rule book by heart.
Do you have any pictures showing a few under the fender shots?
Going to try and take my bars a little more foward going thru the dash, we will see.
I am going to try and tie the upper shock tower into the forward bars and possibly do a coil over conversion at the same time. I am not stuck on it as of yet though, we will see what happens.
