I currently have two final drive kits, a used Prodrive part #15203 (I have no clue whether its a 4.7 or 4.9) The second is a SRR 4.929 and I'm not sure if its a direct fit or if you need some JDM honda parts like the ATS kits need to make it work.

I have tried to reach Prodrive without success (I think their out of business) If anyone can help me out with my problems or has some contacts please let me know.
