took awhile but here's mine, just had to cut a slot in the lower left of the receiver and grind down the large circular area on the lever that would normally stick out of the rifle, you could also just drill the selector hole out larger - also, i tried using the right hand side lever that came with the rifle and modifying it, this did not work well. in fact, i tried the original hungarian, and also romanian and chinese selectors - once i accquired the correct right side lever from a galil that had the same style thumb selector, everything fit together perfectly. also that tapco retaining plate was a crucial bit
a wire shepards crook just doesnt fit, in fact everything fits -very- tightly together and it takes a small bit of effort to get it all into place in an akm receiver without bending anything...well effort, and swearing. you have to have 3 hands basically, and insert everything at just the right angles then rotate and lock into place.
note also that there is yet another type of galil thumb selector lever other than the style i have and briansmithwins above, which uses a linkage and a specialised grip nut with a pivot point on it so that throwing the thumb selector forward takes the safety off and pulling back puts it on.
with both mine and briansmithwins, forward is safe and rear is fire. some people complain that operating it with the thumb in this way is difficult, but if you do install it right its smooth. you can also drill out the small detent on the right side lever where it hits the indentations on the receiver, and place a small ball bearing there - this will smooth things out considerably and is planned for this particular rifle as well.
