I worked a little on my Uncle's '61 W100 today. It's been sitting quite a while. I did a complete brake job two summers ago and one of the wheel cylinders had developed a leak, so we took the wheel cylinder apart and found that both of the pistons were facing the same way. The wheel cyls were new when I put them on but who ever put it together from the factory put them in wrong. Anyways we also had to replace the lower front transfer case seal which had also developed a leak from sitting so long. Hopefully we can run it around tomorrow. It has a '70 340 from a Cuda I believe. Here's some pics of it on the lift:
