Any advice on 727 install?

I looked on the front balancer and there are no words on it. There appears to be a thin small weight on the old convertor and the new one in about the same location…the new one appears to have a little more weight than what I took off. The holes are the same pattern and the bolt size is the same. I did notice a small stud on the original convertor that matches up with a hole in the flex plate on the back of the engine. The new convertor does not have a stud, but there is a stamp mark near the hole that's offset…I plan to mark and the plate more conspicuous. Thanks for all the help…please let me know if you can think of anything else….I plan to put the tranny in the car the first week of March.
