Hello Ralf,
Here is what I have (fastback SJ).
I have measured everything in mm (in stead off inches), but for those who want to see and convert everything to inches, I have taken pictures (see annexe).
It's starts from left to right.
I have in totally 5 patches in plastic (see picture 1)
- the first is at 64 mm from the rear wheelwel
- the second is at 386 mm (so there is 322 mm between the first and second patch)
- the third is at 709 mm (so there is 323 mm between the second and third patch)
- the fourth is at 1032 mm (so there is 593 mm between the third and fourth patch)
- the fifth is at 1353 mm (so there is 321 mm between the fourth and fifth patch)
There is a 59 mm gap between the 2 drilled holes (per patch)
The upper hole is at 22 mm measured from the edge of the door (underneath the sill plates)
(Excuse me in advance for not knowing and subscribing all the correct terms
)
Note : I have measured all holes accurately, the showed pictures are just to give you a good impression of what I have measured.
I hope that you have enough information to get started
Kind regards,
Jeroen
