Remove the brake lines and wheels, along with wheel/leg fairings - simple work through. The legs are one bolt in the engine mount, but the challenge is whether the legs are going to slip out or be talked-out.
Saw a friend do a 20-yr plus old RV-6 do this --- more than a day and lots of patience. The problem was patience for the penetrant to soak into the mount sleeves and allow the legs to break loose. And he did it by removing the engine/mount/gear together from the FW and then working on the legs with lots of room to work.
Start with the penetrant early and then it will depend. He used a cherry-picker to lift the plane, wing stands to support it, and tied down the tail (with the engine removed it's required). Plan ahead. Choose an approach that works. Safety first.
