Getting ready to mate the T5 to the 289(both out of the car. Both the vintage block and the late model T5 bell housing have the 2 big guide pins for the block plate to sit on and for the bell housing to line up to the block. Which should I remove? I'm thinking remove them from the bell housing. I know if I do that I need to be careful and press them out(C clamp and socket, no hammer allowed) to ensure that the bell does not get damaged.
