Depending on what you want to do with the car, you can pick which section applies to you. What Jon mentioned in the Stage 1 area is what I do to most of my Datsuns, even the ones with V-8's.
OEM insulators should be fine for what you mentioned... and not sure why you need/want the t3 parts based on what you mentioned in your post.
