Other side repeated today.
Also took the opportunity to fit up the impreza wheel wells and strut towers I've saved. I cut the middle sections of the angle iron frame I tacked on when removing them, then using some more angle as a bridge I clamped them back together. I ended up somehow sacrificing a tape measure doing this, but I'm getting some momentum back in this project so if a cheap tape measure is the cost to get this back on the ground sooner over later I'm glad to pay it.
I'll need to do a little more surgery to get them to fit truly properly, especially since the filler neck is on the opposite side of the vehicle, but I suppose if I'm doing this much fabrication that will be somewhat trivial. I'll also likely be cutting a lot of them out to fix some rust in them anyway, but it's a good start.
Going to set this aside for a little while and return to the subframe setup. Any permanent install of these towers here is severely premature. Once I have a base I can measure from to get the strut towers to a proper height and location, I can start poking at this in more detail.
