I just ordered a Wilwood rear disk brake upgrade kit for my 63. I was told that the kit that bolts up to the stock 8.2 10 bolt rear end does not come with an emergency brake option. When I questioned this, the salesperson stated that is pretty common when using an automatic transmission and that lots of folks go this route. I just never considered not having an emergency brake. What do you guys think? Anyone else not running an emergency brake?
