just got off the phone with Tilton techline.
He said the 400 series bearing is a bad idea because of the large retainer hole in the bellhousing, they are made for something like 4,6" hole and i have 4,8", i actually measured it and it would bolt up but the inner edge of the four mounting bosses would hang over the hole in the bell. Not a big problem to me but...
So i asked him if there are any other options avaliable for mopar and he said NONE.
Then why do they have the 600 series for Mopar?????????????
Im close to just stick with the stock linkage.
