Maybe it's close the the figures in the 4 Wheel Drives catalogue 40:1 compared to 39.5:1 which would give a 1.25% change. Maybe that's considered insignificant ?

Except that stock is 40.65:1, which makes 3% change. Still small, but it could make a big difference offroad.

I have encountered hills I couldn't reverse up in reverse low in a 109 IIA with a load on - despite me having the lower suffix B gears.

Many people suggest doing this, but it is not a good idea, because the function of the dowels is to hold the box in perfect alignment with the centre-line of the crankshaft. The bolts/studs cannot do this because they sit in clearance holes, unlike the dowels. Removing them opens the way to gearbox problems, such as slipping out of gear.

It is not a big deal to drill one new hole for one of the dowels, the other one on my S3 matched with a pre-existing hole,
