Power vs Manual Shafts

post some pics of what you have and we should be able to help you out.
i have a pic of a manual shaft with the coupler on it measures 42.5" WITH the coupler attached. thats from tip of the steering wheel threads to end of the coupler.

Keep in mind that the coupler slides, the measurements I gave are without the coupler. Is the 42.5" with the coupler all the way collapsed, or extended?
