69 GTO, orig code WF 10 bolt, 3.23 open rear.
I like the ratio for cruising, but need a posi (don't we all?). My father-in-law's gear guy says he can add an Eaton posi unit to this rear for around $500. Sounds reasonable - has anyone else done this? Any recommendations on other types of add-on posi units?
Would I be ahead of the game to just spend more and put in a 12 bolt? I don't plan to race or abuse the drivetrain, but some occasional hard driving is necessary to cleanse the soul. If so, anyone happen to know where to find a reasonably priced 12 bolt posi between 3.08 and 3.36?
Thanks!
Chris
