What was the end result with 15mm did the drums go far enough that the whole brake shoe fits inside the drum. I got 14mm out from the outer surface and it looked like it went really close and I am not sure is shoe inside or not, but as I was in a rush I just installed it and will take it out during the winter. But I think the best option is to take 2mm from the inside and 13mm from the outside. And I used new CSP drums for the modification. But I will return to this once I get the drum out at some point.

Um, just the outer side needs to be trimmed off so that the axle nut can be torqued down and then a cotter pin added. Otherwise, there's no way to put the cotter pin through the axle since the castle portion of the axle nut won't be down enough. Everything else is exactly same.
Did you swap out your axle bearing caps? |

Yup, just the outside needs to be trimmed (the difference in the length of the splines). If you trim any from the inside, you'll put the brake shoes into the drum when tightening the big axle nut (wide 5 or 4 lug), and the wheel assembly may not turn.
I did this swap on a 66 type 1 Ghia, and used short 64 bug axles, and drums that had the 15mm already taken off. Everything worked just fine.

Yes I have the correct bearing caps otherwise the sealing would not work.
And you if you do not shorten from the outside you would not be able to put the cotter pin trough the axle nut and the axle.
But this is not the issue.
Issue is that the drum might not go close enough to the backing plate what defines the location of the shoes. I do not know is the issue only with aftermarket drums or also with originals. And this is only few millimeters that would need to be taken from the inside.
And I will take pictures of the issue once I get my car to the winter storage.

| There seems to be some tolerances when using aftermarket parts. I used 5/130 Type 1 drums on the back of my short-axle Type 3 and I had to take 3 mm on the inside of the drum and 13 mm on the outside. Otherwise the drum was too far away from the backing plate. |

Hey doods! Bringing this thread back to life. The future is now. Write ups are a thing of the past, so I made a Short Axle Swap video. Of course, this only applies to my specific year, and for what I specifically want. Yours might differ
