Unfortunately, the first time the TTI system was installed was by a local shop, if they did any cutting I am not aware of it. When I shimmed the passenger side motor mount, I used a carpenter's level in order to get the motor just right (photo #1). The shop never used a shim and they set it up so the whole system hung too low. I re-installed everything TTI and improved the fit during the recent restoration. Here is a photo of the "H" pipe from my build thread if that helps (photo #2).
