Your guess is as good as ours.
I dont think anyone can tell you what car its for by just looking at the bolt patterns. I suggest you ask the person that sold it to you and if he doesnt know, have him ask the person who he purchased it from. If its any help they look to be manufactured by Decah but not redone to fit the Celica because the bolt patterns look to be off, just take a look at the pictures below from Satoshis hinges. Looks to be the same shape but the bolt patterns are way off. If I were to take a wild guess I would say either Honda Civic or Acura Integra because those are the two cars that Decah makes the lambo hinges for and then they are redone to fit other cars. Maybe you should contact Decah and send them the pics. Decah has GREAT customer service and I'm sure they would be glad to help you out. But before you contact them you might also want to look for several other clues to see if you could determine the manufacturer. For example:
Check the lift supports/shocks for manufactures name?
They look to be the same shape as yours.
But as I mentioned before the bolt patterns are way off.
Hope this helped out...
