I used the same along with the Mancini billet retainer.It did the job. I also welded up the crank because mine was on the low side where the seal sits. All in all it was a pain but finally stopped leaking. And yes the fastfish one piece seal that Jim sold me worked great. On a side note the seals we get today are very different than the old ones. I compared it and the old ones had more "MEAT" on them. I guess production got cheaper.
