Some fun I ran into with the 318's exhaust yesterday.
Haven't had a chance yet to install the new exhaust on my '74 yet, but I thought I'd least fix a leak between the driver's side manifold and the downpipe by tightening up the bolts. The castle nut on the forward bolt, however, is rusted in place. I hit it with a shot of PB, let it soak, then tried to get a socket on the bolt head. None of my 6-points would fit, SAE or metric. A 5/8s 12-point would fit, but the head would turn inside of it. Thanks to how it's angled up towards the block, I couldn't get a pair of vice grips on it.
With the sun setting, I drove it back over to the storage unit. A fight for another day.
