Recently blew the diff and broke the case on my gsr trans, picked up a complete ls trans for cheap. Plan on putting the gsr gears in the ls case but don’t want to use the 64 tooth ring gear. I’ve heard the gsr 66 tooth ring gear won’t work as the bolt pattern is different. Is there any other options for 66 tooth gears that will bolt to an ls diff?

 

I answered this very clearly in your other post... why did you post your question again in another sub-forum ?
