As far as I know they are the same. I used a cut down ARP 135-2503 on mine, which is 1/2-20 thread.

Pics of it on your. Motor . Looks to be a big arse bolt head?

I don't really have a great pic of it. I only have this one:

It has a 1/2" square drive which is really nice. You don't have to worry about the ratchet falling off.

That's what I was looking for. Digging it! Like I said I thought it was only a dang bolt head, nice to have the 1/2" rachet portion to
