Jeffery, I have looked back to the original post, HERE, and as you can see, you are the one who originally said that the one with the I was your original MKII.

The one with the I is a MKII, not a MKIII, and would be most likely a 1971 base, I believe your seized original motor confirms this.

the one With one post is a MKI, not a MKII, and is a 1970 base, I have it's engine here.

The MKIII is the one with the belt guides.

Cheers
Ty
