Sorry to resurrect an old thread..
Did you have any issues with the Spigot bearing for the gearbox? (what parts did you need)
I have a Daihatsu in a a RR Classic 1983 (Ex V8) The timing belt snapped
So have purchased a replacement engine to go in, all going well and fine until the spigot bearings, Cant get the original daihatsu spigot out (new engine) (have resorted to drilling it out, And now can't get what looks like a sleeve for the brass spigot out (from the original engine), (The Brass popped right out with the Hydrolic Grease meathod.)
Any help would be greatly appreciated after 4 hours of playing with them............
