replace starter wires

[Redranger89]

I had found the my red wire to the starter was pinched flat between the block and the satrter. Then i noticed that my ground wire to the starter was broken off at the eyelet on the stud. that was wy my new batery was shorting every time i tried to connect it. and also how the old one drained. I was wondering the procedure to replace the two cables. how difficult is this to do with minimal tools seeing how it is my college parking lot. any help would be great. thanks alot
