My O2 housing actually doesn't contact my steering shaft at all; I'm using the stock R32 skyline crossmember and mounts, and I have about 1/4 inch of clearance between the housing and the shaft. It looks like enough clearance to me; what do you guys think? Is 1/4" enough, or should I try to dremel some of the housing away and give it some more room in case the engine shifts during hard cornering?
