I am still on the fence between the electric PS and a Borgeson box. There is are a couple of builds on here with the electric PS up under the dash. Look for the Gen1 Hemi, he had a picture.
I think I saw one on an early A here in the past, but haven't dug around too much yet. I think there are a couple of good places it might fit, but without one in hand it's hard to say. Mostly thought it would be nice to mount it at the firewall since you need something for it to "push against" for the assist. Either that or the column mount itself seem like good candidates, but I think the column mount might be harder to work around as it's pretty shallow and not sure which direction the motor could face. May just have to keep my eyes out and see if I can pick up a box super cheap to hold up and test fit with. Maybe I can put my 3D scanner to good use and scan the area to get an idea of clearances one of these days. I've got lots of ideas of things to scan on the Dart with it in the past few weeks.
