Hi Joe, I read that you replaced one of your exhaust manifolds. My 66 has a cracked exhaust manifold on the passenger side of the motor. I have made repairs to it but nothing works long enough. Any advice on getting the manifold off besides the usual hit all of the bolts with PB Blaster a few times before backing them out? Did you have any bolts break on you? Were you able to access all of the bolts? Thanks
