I don't want to step on any toes here on Hybrid but the machine shop that I took the bell housing to also did all of Chris's motor work (blue turbo 240z in my videos) That machine shop put the mazworx adapter plate into their computer and said he would make me more adapter plates for $150 just incase Chris wanted one for his car. Mazworx sold me the plate for $300. Now Garrett said that his Mazworx plate flexes a bit when you push the clutch, but its nothing to worry about. I had every intention to buy Austin's (240hoke) plate but he was out at the time. I believe his are a bit thicker/stronger?? But what I'm saying is if you had the RB bolt pattern mayby they could do something for you, I don't know?
