Found these push in Sierra push in drive shafts in the back of the garage that look to be in good condition, don't know what there worth, make me an offer. I'm not sure how to post images.. I'm over 60! but I could send images to your phone.

I'm interested, but there are two sizes! Could you measure the diameter if the stepped up bit that sits in the oil seal at the different end please?

There are three steps on the diff end. Splined section step is 30mm the next step is 43mm and the last one is 61.6mm, hope this helps.

Thanks for checking, I am after the smaller ones with a 40 mm step not 43.
