in the past i have seen NEW bare blocks from chrysler come with NO block to trans lineament dowels. with out them the converter flex plate will NOT last. if you you have access to good tooling dowels a 1/2 should work and you can make them a little longer than stock.

And make sure you measure the i.d of the hole.
You may need to ream the hole for them with a .499 reamer so you only use a .001 press fit..........or risk cracking the ear on the bottom of the block.
