For the sake of knowledge, think of this as the GPan before there was a GPan. This a steel higher capacity pan, with a one way flap / baffle to keep the oil in place for the pick up tube. This was made for "Forced Fed" by a third party. Forced Fed itself has gone out of business but was big for quite awhile. May be some more of these from via the Celica forums.
Note Forced Fed also did a redo of the stock pan, which would be less desirable ... the flimsy stock pan was cut, an extension welded on to hold more oil and a baffle welded in.
You'd want to look for one that was purpose built, one piece/not frankenwelded together.
I've been in discussion with the seller and we've got a done deal. Between my BOE end links, this pan and a gas can to top off the tank, I'll be set for the track
