changed 318 to a 360 in the 38 but left 318 trans in so instead of welding weights on converter my brother had a flex plate from summit i could use well put it in and starter just spins flex plate was used with a 727 my tran is a 904 the cylinder that pushes the gear in hits about 1/8 to big so is there a light weight starter that might clear or does summit sell a flex plate for a 904 or weld weights to converter??did't really want to drop tranny again Thanks
