It is time to replace the rear universal joit on my Hertz car. Does anyone have a part number? A search of the topic on this site did not bring up any information. Any help appreciated. Thanks.
Roy,
Try Dead Nuts On. Don't think there is any better.

Road,
Which series U-joint is going to fit a 9" rear behid a 289 Hi-Po? Would that be a 1330 series or something else? I know the basic Ford number is 4635 but are we talking something like a C3AZ or something else?
Regular HiPo Mustang part. Sometimes you may encounter one that isn't the same width both directions. Those are 1310-1330. Crawl under with a tape and measure both widths and cup dia to make sure someone hasn't changed something over the years.
4635 is the number Ford used for all U joints. The C3AZ tells you the year and model used on. The last - A, B, etc may come into play C3AZ-4635 may be for a Falcon. C3AZ-4635-A could be for a V8 Falcon. C3AZ-4635-B could be for a HiPo V8 with 9" rear.
Just measure what you've got and hit a local real auto parts store.

98SVT, Thanks for the reply. FYI, I'm pretty familiar with the Ford numbering system, having delt with it since 1973. A C3AZ part was probably designed for Ford's Galaxy line but might have applcation elseware. That's why you need the MPC. Unfortunately, a few of the sections of my MPC have been missplaced, which is why I asked. Pretty sure that the UJ is orriginal, at least I didn't change it out. Who knows what was done to it between the PO and the time I got my hans on it. Yes, I always thought that it was a regular Hi-Po part and not a Shelby pecific part. Thanks again.
Roy,
Your car takes a C5DZ-4635-A rear u-joint. 1260-3 15/32" span.
The front is a C5DZ-4635-B. The same specs are listed. a good parts store should be able to convert those numbers to whats currently available.
