So i scored this hitch from a coupe and i wanna put it on my hatch. mostly just for another good tow spot but will probably pull my mt bike too.

it didn't have the bolts with it, what size bolts do i need. i have a welder cuz i read that the hitch doesn't fit right, so i will be cutting and welding.

also, no one tell me i can't pull stuff with my hatch.
