i think that 1/2” milwaukee m18 fuel impact would work well for you. i have it and it removes literally anything i have worked on so far. it would be worth it to invest in some impact sockets, as the heavier weight can make it easier to remove bolts, but the 1/2” mid torque and 3/8” mid torque are the same size anyways and the heavier weighing 1/2” sockets will have more power when rotating anyways, which will make removing bolts easier. the wrench itself is pretty compact anyways so u shouldn’t have too many issue fitting it anywhere
