Hello, again bothering, this day I takes him some pictures to my CJ3A and I could check measures of the wooden blocks and their location, I go up the pictures so that you can appreciate it, the dimensions of the blocks that I have are 11.2x3.8x4 centimeters of high, both are located at the same distance of the hood center (33 cm) and to 3.5 centimeters of the hood edge, I understand that starting from the CJ3A this is therefore the wipers they already go located in the low part from the windshield contrary to the previous models where were up and for that reason it was necessary to put the blocks at different distances, I also find that the blocks of the CJ3A are more high that those of the other ones, I will thank a lot if somebody can give me a small drawing with the correct dimensions for the CJ3A, it could send this way them to make since I know a good carpenter, I wait their comments, greetings.
