Thank you for all the responses and tips. I did trim the mount reinforcement yesterday so I should be OK for access and mounting.
I did have a rare and brief moment of clarity this morning – I’ve been talking to you guys about doing the subframe bushings, and dropping the sub frame will give me the easiest possible access to weld the reinforcement in place, right? In other words-actually do the welding with the Supremes out to make it easy, correct?
