The Series MM does have 4 1/2in pcd and the later SII on has 4in pcd.
If you have 4in on a Series MM you must have the later brakes and rear axle.

All the MM's & first few serise II cars had morris dirived running gear, which is different to the later Austin sourced parts common to A30 etc, the brakes & hubs are different designs although the same size.
The 4,5" PCD is common to mainy other Morris & MG cars of the period & later, and even the early toyota celica! I used the 4J wheels from a 62 morris oxford which take the Minor1000 hubcaps, although i had to modify the angle of the taperd part of the bolt to match the wheel. I have seen period photos with what look like MG A 15" wheels fitted.
The bolts are fragile but not a fragile as the MM wheel, I have have seen several cars loose their wheels! this is because the hole in the wheel centre is not to too strong & opens up with wear untill the bolt pulls through!
The Solution i employed was to manufacture a special tapered washer to sit under the bolt head & make up for the lost metal.
I have also seen hardened studs (with nuts) from modern cars inserted into the holes in the brake drum/hub. an option to considder if you have a stripped thread & no spare, unfortunatley a common probelm when a garrage uses powerful air tools to tighten the bolts!

Maybe I should point out that the idea of adding a tapered washer is to prevent the problem, not to repair a damaged wheel!
The idea is that a washer (thin enough not to prevet the bolt thread engaging in the wheel), will provide a sacraficial wear surface & prevent the holes becoming worn from repeted weel removal to the point where the bolt is loose in the wheel.
I started with soft mild seteel washers simply formed under the bolt, & a dab of loctite to stop them dropping off when the bolt was undone, I was not to happy as the washers often cracked, so I had a set of special taperd washers made, my wheels seam to have survived without the holes getting worn.
If you never take them off then there is no wear!
