I buy mine locally from a tranny supplier , the complete brg & gasket set is $150 range & about $40 more with syncros , I use Passon for any of the extra pieces that wear that are not supplied in the kits such as Syncro keys ,shift forks & springs , if you are doing an OD Mopar still has the plugs for the counter shaft
I have never had a problem with any part supplied by Passion & they are great to deal with & really know their stuff
