Replacement for THK GSR20T LM Block and rails

Are there any LM blocks that use M5 screws and have the same screw layout?

The rails also need to work with the existing anchor holes, which are also M5.

Let me see when i have some 20 minutes of free time to search the web for the THK specifications as PDF and another 10 minutes to sift through them to find the hole raster.

The following pertains to several topic where you keep refusing to provide the required info, so a friendly advice, stop shooting yourself in the foot consistently and get us the info so we can help you, i have at least 10 types of rails and carriages, i mostly know their hole raster for all of them, i can not help you as i do not have time to do the work you are supposed to do.
Some examples:
HiWin HGR25 has a 60mm M6 rail raster and 35mm M6 carriage raster
THK35 has 80mm M8 rail raster and 45x55mm M8 carriage raster
THK45 has also 80mm but M10 ratser and 55x35-35mm 3 rows of M10 carriage raster
Now i can miss something, but i have them, so i can easily recheck.
