Ok, I've read Ken's sticky and other posts. I have an older PTS Killer street from a board member 8 yrs ago. 1) what's the plastic tube for on the case top side? 2) D5 tc, case has a two post electrical connector. Is that sufficient for 4th gear lockup? If so, which post to what? 3) can I hook the pressure gauge to the 90° elbow above the shift linkage arm on the trans case to set TV cable? I already have TCI carb bracket fitment issues. Hitting brake booster vacuum port and manifold even with 1" carb spacer. I have column shift 455/th400 in car now. Stock manifold. Longer carb studs coming to move bracket up 1/2" more.
