does any place still do that?If you remove them you could have the wheels and tires ballanced on the car.
I would expect high end / performance shops have the tools.does any place still do that?
Can someone explain specifically why weights were put on the drums?... I mean I figure it is for balancing but the weight would have to be mounted before the wheels so does that mean the weight is just to balance the brake drum itself
Exactly. I have a little vibration but I couldn't tell you if it's the tires and wheels I installed (they were balanced already but I didn't check them) or something else. Whatever it is, it's not bad enough to worry about.You hit the nail on the head.
What I can't understand is how they can cast a drum and it be so much out of Balance that it requires 2 - 2" long 3/8" thick weights
...
So thinking there may be a bushing in the end of the transmission that is worn?
...Anyone know if that is what keeps the transmission output shaft/yoke from wobbling during rotation?
(Maybe I should start a new thread- Sorry don't want to hijack this thread but may be useful for others trying to diagnose vibration issues)

Because only the inside is machined. The sand cast outside is left as-cast. There is probably a lot of run-out between the ID and the OD. The factory made them as fast as possible. Probably faster/easier to add balance weights later than it would have been to machine them more carefully on the lathes.You hit the nail on the head.
