in too deep: trying to go BBP on a 68 barracuda and its going.. poorly.

No doubt! It depends on how you’re going to use the car. If it’s an infrequent driver that only sees the road in good conditions then the drums are ok.

For me, if you’re planning on doing regular driving, or driving in traffic, adverse conditions, etc then an upgrade is in order. I drive in too much traffic to trust all the knuckleheads around me will do the right thing
...and that last paragraph reminds me of what Daddy drilled into my head talking about driving. He always said "watch the other fella" and he was dead right.
