2H diesel conversion to F gas

Maybe someone can tell me. I have a 2H diesel in my Toyota forklift, haven't been able to get it started, been settin' for 5 years. I also have a spare, very good 1F gas engine on the floor. I'm needing to know if the bolt pattern for the bellhousing on the 2H is the same as the 1F. Also need to know if the crankshaft/flywheel bolt pattern is the same. In other words, will the 1F bolt up to the 2H bellhousing and will the flywheel from the 2H bolt up to a 1F?

Forget it, the two top bolts are spaced differently. The 2H is about 5" center to center and the 1F is about 5 1/2". Was going to delete this post but thought maybe someone else may want to know.
