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.

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.

Thanks, Marty. Best advice to work with yet.
