Will a Manual 99 Gst Eclipse 7Bolt ShortBlock fit in my Automatic 99 Gst Eclipse!?
Yes it will. The block itself is the same between manual and auto. But the crank in the manual short block will require a pilot bushing. You can remove it from your old engine that was with the auto trans and reuse it. But usually it's a PITA to remove since it's press fitted, so maybe you should prepare another one. Like the one in the link below. (OEM is discontinued)
