Need some help with timming belt stuff
 

Hey guys, I am a student and new to the forum. I need some help big time. I was drinving along in my 1994 mazda B2300 2.3 L doing about 40kms all the sudden the Fu*^ing timing blet broke I am sure a few of you guys can relate how frustruating it is, I would like to do the repair myself as I have ok mechanical appitude and have done engine swaps, transmission clutch, lines electrical, etc... except I have never delt with the internal workings of an engine nor the timing belts. I enjoy working on trucks and its cheaper if I do it as well. The probem is that I am having trouble re-aligning and finding the marks, I cant find them what do they look like? the manual only helps so much. I dont know much about timing belts in general I have never done one, any tips and tricks or break downs for my engine would be very much appreciated. I am lost with the whole thing but really would like to learn how to fix the beast. Again thanks
