Verified ownerWould recommend to everyone, very easy to remove the original mount to replace with the new one.
Verified ownerThe part looks excellent and came very well packed. The part was fairly easy to install. I would have given it 5 stars however, I had to widen the bolt holes to fit the OEM differential bolt studs and the vehicle frame bolt studs. I would recommend this part to anyone with a Z31 and looking to upgrade old out-of-stock differential mounts. After driving the mount felt very solid. I did not feel an play or movement in the differential.
Verified ownerHad to dremel all the holes out,mainly due to red hammer coating I think but had to take away just a tad of metal as well to get fitment right. For the price of course I expected perfect fit.But also expect custom parts like this to sometimes need a little work done for fitment. Overall very satisfied can’t find a upgraded poly diff bushing anywhere else!
