My plan is to get the running gear in it by Friday, finish the paint next weekend and make room in the shop for some paying work. The 409 has valve covers with no breathers or oil fill, thinking I will weld in bung for the pcv valve and pull the cover to add oil. So whats the deal with twin stick for transfer case? Don't think it applies because everything is electronic on it - well I guess you still pull the lever on the floor to put it in 4WD.
