The drivers side did not line up. Had my local mech do a little welding.
I did not have to take the W58 out. In fact I did install them with the W58 out figuring it would be way easier as I had the tranny out, and had to undo the nuts to really loose on the passenger side header to get the tranny back in. Luckily the passenger side is much easier to get to the nuts.
LOL I reread the thread and see I already said this. Bartledoo, I don't think you will have to take out the W58 to do the install. It is tight though and you will want to have all manner of 14mm wrenches... short , long, curved etc
