The yoke from the 1G is a humungus bloody thing. No it will not fit a W series box. However all W series boxes share the same yolk. You can pick one up from just about any Celica that does not have a 2T/3T. Mind you if it has a 3TGT, you are in luck. So basically any RWD Celica past late 1976, with an R or S engine.
