Well, Loretta let me down for the first time in 5 years today, grenaded her rear UJ on a trip to the dump. Thankfully I have recovery as part of my insurance. She was a small block car originally, although she came to me with a 440. I'm sure I've read somewhere that there are different sized UJs, presumably for small and big bock cars ? I'm assuming she'd have the small ones, (they looked pretty weedy) Does anyone know what's involved to upgrade while its in bits?

Prop, Yoke, and Differential Yoke change to 7290 or bigger.

Cheapest option is a combination joint on the rear but hat leave a weak point....

I went down this route when i changed the rear axle and the prop no longer fitted.
As pete says you can get a conversion UJ ( i might even have one in the spares pile) but i decided to get it all matching strength in the end. Hausers made me a new prop and it wasnyt bank-breaking.

The smaller 7260 UJ came on most things I think, for general road use I wouldn’t consider an upgrade to larger UJ’s to be needed. Just replace with the solid body non greasable type and be done with it.
