Well in my case the coupler would not clear the last tube at all, it would hit. What i read was some people shim the steering box over, use an aftermarket U-joint coupler, or dent the tube. I didn't like any of those options. I ended up (to the tune of $600) bought a Flaming River drop in B-body steering column and other that having to cut the shaft shorter, it all bolted in. The universal cleared and all is good and I gained tilt. I didn't exactly want o shell out $600 for this but I get a sliding steering shaft, tilt and don't have to shim the box or beat the tube. I have found where people had no issue with the stock coupler fitting so just be ready if it does not. I will say the stock steering wheel will fit the Flaming fiver column if you grind out the key spline but the fit between them leaves gaps.
