Exactly the same as the factory tub. I tore out my rear suspension in a crash, this replacement got me back on the road! Includes all factory stickers pre-applied (on/off switch, 7.2v on battery tray, etc.) and all tt-01 cars use this tub (mine was a type E). It's cheap enough to pick one up just in case.
Because the suspension mounts are part of the bathtub chassis, a new chassis will eliminate slop in an older car. Plus, if you've stripped or cracked some screw holes, this will get you back on the road.
It's a shame there isn't a carbon reinforced or carbon fibre chassis available. So this is the best you can get!
