I am in the process converting my Zed from auto to manual. After reading the article on another forum site, http://www.300zxclub.com/showthread.php?t=85616, the removal of the pilot bush, so far, has given me the most grief. A slide hammer didn't work for me. I used grease and an old shaft from my ride on mower. Simply put some grease in the hole and push is the shaft. The shaft was snug but could be pulled out by hand. I used a sledge hammer, and after a few bashes, the bushing pop out. The whole process took less than two minutes. I have been told it works just as well on spigot bearings. I hope other Zedders find this useful.
as long as the shaft is the right diameter (and a close fit) then you can use most viscous substances. I've even heard of people using torn-up crumbs of bread
you need a large masonry chisel, and a small hand mallet with a bit of weight to it, stick the chisel on the inside lip (the bit the gearbox shaft goes into) to the pilot bush and whack it hard, it should pop out in a few hits, do not damage the crank, and do not attack the outside edge of the bush. This has worked for me
