BB Install Questions.....

I bought a stud remover today. We will try that.

One more specific question:

I have a 74 /6 crossmember. I cut the drivers side perch down, and am now ready to install.

Did I need to cut for OP clearance or what? I can find no mention of it in my instructions, but it has been awhile too since I got the kit. Something may be lost etc.

Are the only mods to the car itself just the tower on a 74?

Thank you for your help.
