I cant get any #'s without pulling the trans. I know the retainer is 4 11/16 inches. 4 bolt holes around it
This is novacks billit design
And this is what it looks like on the trans

. I dont know much else. I think mine may be cracked as it is leaking 80/90 out the front pretty bad, either that or the seal is bad. I would like to have both seal and retainer when I pull the trans out so I can just fix it and put it back together.
Thanks
Erik
