How far can front ab overlap?

[TK11057[TK]]

I’m a skinny guy so I added some foam on the inside after reading some suggestions and minimize the overlapping a bit. Would like to know if this is acceptable or will I need to fix. also can the butt plate come up and go over the back plate (it just fits me better) will that be acceptable also? thank you.

If you want that extra width to make you look bigger, and you already have all the foam in there you can stand, you might want to consider adding a kidney tab to stabilize things on the right side.  The tab helps to 'lock' the alignment of the kidney and ab.  Here's what I did on mine (there are many ways to accomplish this, go with what works for you!):

It also looks like your strapping on the inside of the the kidney rivets might be too long, which is allowing the ab and kidney to move around a lot more than it should on the left side.  If you shorten them up a little, that might help with some of the overlap issues.

If things aren't fitting together as they are now, a hot water bath can do the trick to get the pieces into better form for your frame.  The front and back halves of the armor should meet together nicely without any assistance from the belt to pull things together.

I second Cricket's tab idea. I have a similar set up in mine, and it keeps the ab and kidney lined up nicely. 

 

As for your second question, I'm not sure I 100% understand what you are asking, but there shouldn't be any overlap on the back parts.

for the second question if the plate can go like this

The butt plate is not supposed to ride over the kidney and TM  (in your link) gave some great advice on how to fix the issue
