Well my guess is the numbers related to Type 13 and Type 14 (Beetle and Ghia respectively)
Basic gist of it, the KG dash sits in a different position in the shell than a Beetle dash does, so the steering column is at a different angle.... effectively more laid back I think.
As a result the steering box needs to sit at a different angle on the beam to make sure the column is in line with the input shaft on the box.
Rather than having two different brackets, VW made the little offset hole in a slightly different position on each side of the bracket and you just mount them differently for each type of car... pretty clever !!!
👍
Obviously if you put it round the wrong way, the input shaft and steering column won't be in a straight line and the rubber donut will have to try and take it all up...
