If you plan on modding a slingshot 42cm stabilizer to use with the 633, you have two choices. You can Frankenstein mount it like I show in the first post. This works fine and is completely quiet. You'll need to extend the rear hole, the front hole is in the right spot to keep the trim of the stabilizer correct for the 633.

If you want to mount it like stock, you need to fill the holes and notch with epoxy. Then drill the holes again and countersink the other side. Remember to use a countersink with a 90 degree angle. (Metric uses 90 degrees, US wood and machine screws use 82 degrees.) The fluted countersink I had chattered horribly, this one worked great: https://www.amazon.com/gp/product/B00KTTR45Q/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

I also used a jig that I made to hold the stabilizer at the correct angle for the drilling. (Shown in the picture.) It seems pretty important to me to have the hole lined up with the mounting holes... That said, the Moses stabilizer seems to have the holes drilled way off on angle.

The stock position of the front hole on the 42cm stabilizer lines the stab up so that trim is correct. If anything, the trim is such that you can stand just a bit further aft on the board. (Maybe. It's only a tiny bit if anything.) Moving the stabilizer forward requires more front foot pressure, moving it aft requires less front foot pressure. Moving the stabilizer aft also decreases pitch stability; at least it did for me. (Moving the stabilizer fore and aft rotates the stabilizer and changes the trim.)
