I already posted this in the auto trans section before realizing this was here. I have a 64 Skylark convertable with a 2.78 open rear, I just dropped in a 200-4R overdrive and want to go with some bigger gears. What are my options as far as gear ratios? The car is a 3rd car part time driver and I live in Alabama so I don't really need nor care to have a posi (on the rare days of bad weather the car stays in the garage).
