Glad to hear that you have the engine back together and running. Nice to accomplish a project that has been set aside for a while and know that your work and waiting was not in vain. If it was me I would leave the ID plate alone - get things looking too pretty and it might never get used in a future project - just my 1.25 cents.
So true, I probably spend too much time trying to make things look better. I guess it might be because of growing up and watching how my Dad finished his projects. He wouldn't usually bother to pretty things up much, if at all, as long as it worked that was good enough for him. Used to drive me nutz! Just me maybe.
