Hello i recently bought a 70 falcon(early) model it was originally a 200 inline it has a column shifted c4. now my concern is that when im sitting idiling in park the shifter will drop down into reverse ive read that the detent plate is likely worn out along with all the bushings. havent taken it apart yet was wondering what else it could possibly be and where the hell can i find the parts to fix this? what other ford cars may interchange with these parts. thanks alot is my first post here.
