On this page, you will find the manual of 145 and 146, it is online, and they are together, the only thing that can be a problem is that it is in a foreign language, but nothing is not impossible with an internet translator
Thanks for the information, although what I am looking for is the workshop or repair manual, the car manual already I have, anyway I will continue looking for where you have indicated to see if I find something there, I had not thought about looking for it in other languages, thank you very much for your help and there are if there is luck.
