Cluster Gauge Problem!!

Hi.
I have VW Golf MK1 with 1.3 carb engine (GF code) with 4 speed transmission (GU code)
I have changed the cluster gauge from the original to VW golf GLI mk 2 (when i got the cluster trip meter was broken everything else was in working order, then I realize that in 4th gear at 2000rpm the speedometer was showing around 60km\h, then went to a specialist for gauges to fix the trip meter, when i got it back the speedometer was showing 50km\h in 4-th gear and 2000rpm)
Found the gear ratios for my transmission
Final Drive 4.267
1st 3.455
2nd 1.952
3rd 1.250
4th 0.895
I do the math and it turns out that in 4th gear at 2000rpm it should be 57km\h
Here are the clusters
This is the original



And this is the mk2 cluster



My question is does anyone knows the gears in the cluster and their number of teeth should be.

if the cluster came from a 1.6-1.8 thats why, you need to change the speedo for a 1.0-1.3 mk2/scirocco one. the speedo is calibrated differently between big and small block.

make sure its from the same era of clocks, the 90spec single plug speedo wont fit your pre-90 2 plug cluster

I can't say for sure from which engine the cluster came off, because I took it off from golf mk1 with mk2 instruent table, I think the problem is that when I took the cluster to the specialist, he made some mistake with the gearing inside or the speed needle was put back  little more to the left.
I found a manual how to disassemble the speedo and there was warning that the needle should be put back from the zero position.

If you have any advice what should I do
Thanks in advance

the way to tell is the code on the face of the speedo, you can see it near the milometer reset.
MK2 kph 1.0-1.3 - 935
MK2 kph 1.6-1.8 - 950

id assume it would be a big block as it has a rev counter, the small engines mostly had just the analogue clock like your old dash
