yamabond, hondabond, etc are gasket makers. If you have a seal already you don't want to slather it in that stuff (unless the manual tells you to). Occasionally I will use a dab to hold a seal in place while I set up the parts to go around it, but never cover the seal with it.
The weak point in any old honda is going to be the gaskets, espcially the head gasket. The shift seal should be replaceable from the outside, at the best case you remove the circlip and it pops in, worst case you use a drift to seat it.
I use the microfiches here:

looks like all the seals are still available from honda.
