Make sure to write it down this time so you dont mix them up when you are putting them back together.
The one with one post is the MKI i gave you, it goes with the engine that has a serial starting with 52700, which i beleive you have already restored.
The one with the 2 posts is your original MKII, and needs an engine with 52710 on it, as the original (Seized) engine most likely would have had, You should have most of the parts for this engine now, between what you saved of the original engine, and what i have given you, though i do have a dust-seal washer, and a lower crank case for this.
the one with the belt runners is a later MKIII, if you need to replace the cowl for this one, make sure the lip on the cowl, around the starter, is smooth, and continuous.
I have an early MKIII here for you, it is very similar to your MKII base, and must be matched with a cowl of the same type, the lip around the starter hole on this cowl, will have 3 indents, that mark where screws were drilled in for the MKI (as it was cast from the same mold)
