Second gen pedal ratios
So got some measurements for you all on an old pedal and ratios using upper hole for manual(where brake light switch bolts) makes it 6.5:1. Regular power brake hole for single diaphragm booster (11"?) 3.53:1. 79-81 4WD dual diaphragm booster(9"?) 2.8:1
When I first swapped the '81 4WD system on my '78 I kept the same "regular" power brake pedal on the new booster. Stopped good not much feel until I bought the correct 4WD pedal with less ratio.
