Anyone have a NAPA or other interchange number for a 39 junior ujoint for overdrive vehicles? Non OD cars have a smaller diameter ujoint, OD cars have larger. Didn't see one in the cross reference listing.

Front or rear? If this question seems stupid, please realize its been a long day already ...

FlackMaster: I think they are the same, No? To cut to the chase, I am looking to repace both. When I installed the R9 overdrive, I put in new ones but was not smart enough to record the numbers. I can probably take an old one to NAPA and have them look it up based on dimensions.

PS: I'll be watching to see if a 39 Six Sedan project car shows up at Hershey.
