I have had a correct 5335 shifter handle lying around for ten years. Sending it out to be rechromed shortly. Currently my 69 has an incorrect handle that bolts in to the shifter assembly. I am told it is from a firebird of unknown vintage. So to make this correct, do I need a correct replacement shifter assembly with rods and all, or are the rods most likely okay? (I have no idea whatsoever regarding any of this.) I would post pics but my car is elsewhere and about impossible to access. Tempted by gsfred's cobbled together shifter unit if my rods will swap over.
