I am in the very beginning stages of doing a carb 2 TBI conversion on my '79 350 manual K5. I'm not clear what model years I can use for a donor vehicle. From the web and different forums I have 3 different model year ranges that can be used for this swap: 87-91 87-93 87-95 Obviously, the first at a minimum, but the last would be good as there isn't much left in salvage yards, so four more model years helps in selection and availability. Anything special need to be done in allowing for a manual trans? Most donors are auto trans. Thanks.
