The front and rear gearbox you have referred to are designed for savage 25 and you won't be able to get the modern Savage diff shafts (AKA diff cups) through the holes easily. The diff cups of X and XL are 17mm in diameter, the FLM ones are 16mm. On the other hand, the opening in the gearbox you posted are 15mm in diameter which derives from the design decision to use bearings with OD of 16mm while splitting the gearbox along the y axis. They nevertheless made a fatal design flaw choosing to stay with 688 and MR1060 W5 ball bearings (8x16x5mm and 10x16x5mm). They should have gone for 698 and 6800 (8x19x6mm and 10x19x5mm respectively) bearings.

What you can do is remove the 4 screws on the differential gear and try to fit the diff cup from outside the gearbox onto the differential housing... and then tighten the screws through a hole (which you must have drilled beforehand) on the diff housing that lines up exactly on top of those screws. See image 5 enclosed. I think you will go insane before finishing both diffs though. Or you will never think of opening your gearboxes again after installing them...

Your better options are integy diff housings which use 19mm bearings and FLM diff housings which again use 19mm diff housings but which need diff cups that are no larger in diameter than 16mm. FLM's own diff cups are just that but unfortunately they have been outta stock for ever and a day.

Note also that both Integy and FLM provide you with nylon bushings which go around the stock (OD: 16mm) bearings effecticely making their outside diameter 19mm.

There is also RPM which copies the HPI's design (which splits along x axis) for their gearboxes and eradicates the ball bearing and drive cup issues altogether. But for that exact reason it has far less rigidity and the from and the rear parts hardly ever line up exactly. RPM gearboxes are also discontinued and sell for very unreasonable prices these days. See last 2 images enclosed.

The rest of the items you posted are okay actually. Not the hardest aluminium available but OK. The drive shafts are definitely stout. Though every aluminum suspension arm is susceptible to bending in crashes and heavy landings. There I would prefer nylon. But each onto his own.

Let me know if you have any other questions.
