Hey group, I'm new to this, so here it goes. I have a 1981 Jeep CJ5 hat I bought used. It has a 151 Cu inch engine "Iron Duke". I am trying to replace the bell housing, but the two I ordered and got, don't fit the engine I am using. I looked online, and from what I found, it shows that for the Jeep with a 151 cu inch engine I am using it needs a bell housing that fits a Chevy small block engine. Any confirmation of that would be appreciated. Court.
