the simple way to find ped textures in SA-models-gta3...is to download PedEditor....there you can see the peds3d,theyr name,stats..after that you open the img tool...and serch the name of your Ped............and for the cars....Ex:if you have zr350, and you want a jester,you can go in the script file and edit it with SAbuilder..........or just extract the both cars to a folder.....than rename the jester with zr350(dff+txd) and the zr350with the jester(dff+txd)......after that enter img tool and replace the files.....and rebuild archive....dont forget to backup you files....
