I think thats the one I got, but I also bought the top end kit with the turbo cams. One thing I would advise, and mind you I am still kinda of new with turbo's, is to get different rings(mainly cuz Ive heard of so many problems with them, including myself) and get an MLS headgasket.

Be patient, some real pros thats been in this for a while will give some advice aswell.

Good luck

does that same site have a kit for the OEM-spec rebuild for the 420a?

thanks
