No you don't. The only thing you would need to grind off and reweld would be the Passenger side transmission mount on the chassis if you converting from Auro to Manual or vice versa.
The only modification would would do on the drivers side would be "if you wanted to" grind the engine mount down a little to make it fit better, In 4th gens it isn't necessary.
