yet... homeboy up top has the mckinney kit, and it sits perfect... and your kit obviously does not, based on a customers review of the product...
So all you have to do is prove, 100%, that you have installed an rb25, in a 240, with YOUR kit, and it sits right in the center hole, and has no clearance issues...
how about a picture from the top of the shifter hole? and some pictures of the actual mounts, obviously needs to be well lit.
Otherwise, and i dont hesitate to throw this out there... you could be using a kit that well, works. ya know
so uh, do us all a favor and provide that proof, rather than babbling on about your "experience with rbs" ...
