Well that sorta sucked...

They're Dougs. 1 5/8 tubes. I've read a lot of different threads about the install and everyone has done a bit of each of these things. Especially the column. The header was not going into that hole with the shaft or box in there. We had the motor lifted until it was bottoming on the tunnel.

I can't speak as to whether or not the DS would have gone in from below but I'm pretty sure the PS would have fit if we were using a lift.
