My bus made that same noise in 3 and 4 when I got it. Mainshaft bearing was shot from lack of lubrication, case was nearly empty.
A rebuild solved the issue.

| I’m sorry if someone mentioned this but you’ve tightened the bolts where it attaches to the spring plate correct? Mine starts to make a similar noise when they start backing out. Simple stuff first sometimes. |

off gas Noise stops....push the gas and it starts up again
and when going down hill, foot on the gas it comes and goes with bumps in the road if that makes any sense. |
My pinion bearing went bad and made that almost exact noise. It is a preloaded tapered bearing that holds the pinion gear against the crown gear in an exact fit.
When you get on the gas the engine loads the bearing with the force of the horsepower and when you let off on the gas the load goes to the rolling wheels side of the equation.
You probably could go like that for a long time as the damage is already done if that is what is wrong. |

Seeing as how all their photos of swing axle transmissions for a split window bus are IRS transmissions, go ahead and send them your money let us know what happens!
You might try a complete drain of the center section and both reduction boxes, refill with 2 quarts of GL-4 90 wt. gear oil and 1 quart of Lucas oil stabilizer. That's how I rolled with my 66 with a 67 gearbox that had sat up for 20+ years; I started out with 3 quarts cheap Walmart gear oil for about 600 miles then drained that and found the GL-4 and mixed it with the Lucas. Just might quiet things up for you.
Good Luck!

I have no experience with the link you provided.
But If you wanted the best, and most worry free, I would vote for:
https://ranchotransaxles.com/vw-transaxles/
You can have them attach your axles, and use their no-seam axle boots, my Rancho axle boots are 12 years old and like brand new still.
