I would advise against using a stock used 200R4. They are usually junk. They were junk when new. Not going to hold up with any hard use at all. These trannies need to be beefed up to handle a strong V-8.
i agree with jim on this one.go with an original tranny.you will save the next owner of that car alot of grief when he needs to order parts for it and they are worth more if original.if you want late model technology,buy a late model car
