Default Trans jack adapter for diff using Pittsburgh floor jack

Any suggestions for a trans jack adapter for the differential removal, to use on a Pittsburg floor jack and that fits in the jack pad hole. I’ve been looking and there are so many. I was hoping someone has found one that works and where to get it.

unless someone has a better suggestion?

thanks, Steve

Can you rent a Transmission Jack? The tci adapter looks perfect. But if you are rebuilding the differential, you'll most likely use twice, once to get it down, once to put it up.

I cut a 12” diameter circle out of 3/4” plywood. 4 carriage bolts and 2 straps underneath will cinch it to the jack pad. The diff actually self balances on it.

This is what I used to install my differentials. I scoot them under the car and I lay beside the diff. I hold the crossmember with one hand so it won't fall off the jack. Then I raise the jack arm using my leg to pump the jack handle. I can eye ball raising the crossmember/diff so that the end female cups mate into the body male parts. Once I get the crossmember jammed to the body, I then just insert the crossmember end bolts. Easy Peasy.
