i want to change the starter on my dodge ram (2500 diesel 4x4) i have the new starter and everyone that i've talked to has said that it is a simple thing to do. the guide i have only has 5 steps to switch starters around. however the bolts that are holding it in seem bizarre, i cannot seem to get any type of wrench on them at all. i have tried different sizes and styles, metric and imperial, and nothing is working. they don't seem to be normal hexagonal ones instead they seem more like a multi sided star with at least ten "points". is there some type of tool that i'm supposed to be using for them? everything said just use a standard socket or wrench.

also i snapped the small wire that comes off of the starter, can i just put a new end on it and reattach it like normal when i put the new starter in?
