727 or A500 Yoke

My driveshaft guy supplied me with a used 727 yoke after the "new" one that I bought from Summit turned out to be of very poor quality. Fits perfectly into my A500.
I have no experience with the 518 so cant be of any help there.

Ok, so maybe the 727 and A500 are the same. If I don't have any luck here, I will ask the driveline shop.
