I would recommend the newer stock. Scorpyd must have changed the hole location for a reason. The first time I removed my Orion stock the two rear screws were bent. No idea how/why they bent. I replaced them with Stainless Steel screws, since I have no source for Ti screws.

What bolts do you mean by top rail bolts? The ones at the back of the rail for the stock?
The reason they changed the hole location was because they changed the latchbox design in 2017 to it's current configuration. The new latchbox was made to work with both the carbon frames of the Deathstalkers and the aluminum frames of the Aculeus, Nemesis and Tremor.

The stock was also redesigned in 2017 to work on both the carbon frames and the aluminum frames. There are 2 types of forends for the 2017 and later bows. The Deathstalkers and Nemesis use a forend with a standoff molded in to take the place of the under the rail risers on other models. The Aculeus and Tremor use the same forend as the 2012 - 2014 Ventilators, 2014 Orions, 2015 - 2016 Ventilator Extremes, 2015 - early 2017 (pre Aculeus) Orion Extremes.

There MAY have been a change to size and location of the screws into the latch box too.
One screw hole is for a #6 screw, the other for a #8 screw.
Note no serial number, so this may be a prototype part? :unsure: Latch box right side cover plate. View attachment 250335
Here's one from an older Ventilator with only one screw hole for the rail to latch box. View attachment 250336
The previous latchbox design was used from 2009 - 2016/17 production model bows. From 2009 - 2013 not very much changed other than cosmetics, black or silver, some had red SCORPYD and or red scorpions on the side. Up until 2014 when the Orion came out, all the previous models used the same folding stock design where it wrapped around the sides of the frame rail and used the larger / longer screws through the stock, frame and into the latchbox. As we have discussed before, there is no boss on the latchbox around the holes to standoff the frame rail like the current latchbox uses.

2009 - 2012 RDT / SLP / Telson all used the full length folding stocks that just had a cutout for the below the rail riser and finger guards molded into it. In 2012 the new shorter Ventilator came out and they cut the full length folding stocks off in front of the trigger where it met the new 2" closer to the trigger riser. This removed the part of the stock with the trigger guard, so the new lightweight ergonomic forend had the trigger guard molded into it to extend back behind the riser. The 2012 Ventilator was also using the new lighter weight frame rail extrusion with the finger guards extruded in. In 2013, the Velocity came out. It was longer just like the RDT / SLP before it. Basically the same bow, but now had the newer lighter frame rail with finger guards extruded into it like the Ventilator. They still used the original folding stock, but cut it off at the riser, 2" ahead of the Ventilator. This now included the original molded in trigger guard, and a newer forend like the Ventilator design that didn't need the trigger guard molded into it.

In 2014 they introduced the Orion that used a newly designed lightweight non-folding stock. This stock design did not wrap around the side of the frame rail like all the previous models. The 2012 models through 2015 used the lighter weight extrusions with a wide groove down the side of the rail like all the previous models with the original heavier extruded frame rail. This was not as much of a problem with the side screws with the wrap around folding stock. The wrap around stock helped with a little added structural integrity. The latchbox did not have a boss on the sides to fill in the gap to the inner frame rail. If you did not tighten these screws properly, you could actualy cave the sides of the frame rail into the latchbox and/or pull the latchbox off it's nominal centerline. With the new Orion stock design, it presented cosmetic problem and a structural problem with the screw location. If they left the screw in the previous location, you no longer have the wrap around stock, and people would surely overtightening these screws, drawing the side frame rails into the latchbox. The side stock screws were higher and smaller diameter as you are surely aware. They moved the side latchbox screw location higher and back a bit for the Orions and later Orion Extremes. This moved it closer the the stronger part of the side rail closer to the top corner, lessening the chance of overtightening and caving in the frame rail sides. The simple solution would have been to add a boss to the latchbox sides, which they did on the newer latchboxes.

There is a simple not needed fix for the older latchboxes with no boss if you are the analytical OCD type. You can add a washer, Teflon or otherwise to not only help keep the latchbox centered, but to keep someone from overtightening the screws. This gives the latchbox and frame rail marriage a lot more structural integrity. One of the mysteries that I never understood why Scorpyd didn't do one or the other. These side screws need to be screwed in until they are just touching, then alternate evenly on each side to snug them down. Otherwise you will overtightening the first side and the other side will not be to the same torque. This can pull your latchbox slightly to one side, pulling your latch claws off center. With the latch claws perfectly centered you have 0.014" either side of nominal with Q-Nock / U-Nock and shaft diameter.

After the 2014 and 2015 model years with the extruded in grooves, they changed the frame rail extrusion in 2016, removing the frame rail side grooves. The frame rails have had smooth sides since the 2016 model year. In 2017 the new latchbox came out and the new stock design with the side screws mounted in the center of the side frame rail. The newer 2017 and later latchboxes have a boss on each side that extends out to the inner frame rail wall for greater structural integrity and keep it centered. It's also much more cosmetically appealing to the eye, IMO.
