Just curious, why you would have to relocate your NSS? I have a 69 and I put a 2004R in it and had to move my NSS from the steering column to the slapstick housing since the rod linkage from the tranny to the column wouldnt work with a overdrive tranny. Got my NSS conversion for my slapstick at Shiftworks. Is the console smaller in a 68 then the 69 console?
I relocated it because the slapstick didn't have the tabs that the NSS screwed into. I also bought the American autowire upgrade kit that relocates the NSS to the shift linkage on the TH400. Console is the same size 68 or 69
