Clearing the oil pan and k member

Start at the begining. Check everything that relates to engine-trans alignment.
Moter mount brackets on the correct sides of the ears.
Correct bisquits (motor mounts)
Correct trans mount ( is '65 directional? it might be)
I verified the brackets first, by the book. I definitely have the right mounts because the ones I ordered the first time were wrong as they were listed incorrectly. Then we had to make sure they were in the correct orientation. Trans mount is an exact match and we unbolted the trans cross member to allow for movement to align things better. I'm gonna heed the advice of loosening the mounts and sitting it down and tightening back up once in place. The damn oil pan is just so close to the k member, im gonna damage something if I dont get it right.
