I'm building an MC-30 (also maybe an MC10-20) and have plenty of parts
- except all my end plates appear to be for 101's, and don't match (for instance the "MCR30?") IPL.

There are two MC-30 IPL's that show two different LOOKING end plates
-though the part numbers listed (57768A) are the same -
EXCEPT for that of the inner seal
(the "MCR30 IPL" shows #57784
vs. the "MC30 IPL" 's #57897 -SAME AS THE MC101 !)

The insertable part of the end plates I have seem to be somewhat ovalled at one point,
and have a boss (or "tit") on them, and that part of the plate shown in the MCR30 IPL looks round.
Are all the super end plates interchangeable or not?

If not, what can I use for the MC-30 (and how would a seller of a real
#57768A even know what part number he had, as they're not marked?)

-And for an MC10 -orMC20?

Please note: I don't care about the ignition issue at all.
I'll probably get around it initially either by using some of those MANY small parts
from the 1-71/81 I have or some of the SS modules I also have.
I will NOT be doing actual pushrod on the -10 when I do it.
I do also have a few points sets.

I think you can use any of the side covers for the Mc30. Where you get into trouble is if you try to put an early side cover on an Mc70-100 that have a longer stroke and full skirt piston. Those side covers have a deeper flat for piston skirt clearance. With the 101 there is a notch in the piston for the boost ports so the flat doesn't have to be cut as deep. Just the Mc70-100 with a full skirt piston needs the deeper flat.
