It is mounted right in the middle of the flywheel cover. As for spacing, you need to cut out a spacer from the panel it comes attached to, as seen below and it will line right up and won't rub the flywheel or the washer. You can take a pawl off another pullstart and flip it to avoid using the fender washer. I rock the fender washer, but I don't bend it. I cut it like pictured below so the pawl hits it in four spots and then rather than bend it up to catch, I just threw a washer under it. You want to make sure that everything lines up well where the pawl hits the washer though as it is thin and if it is off it will tear up the pawl and make it slip on you. Now that I have that all ironed out (after ruining a pawl because my washer wasn't centered well and buying one to replace it), my only problem is the cheap shitty line breaks occasionally, but it is a five minute fix on the side of the road so it isn't a big deal. Outside of that, it is surprisingly durable and totally worth doing because that starter clutch sucks ass and makes your rpms hang.
