you will need 2 gasket kits 1- 54 kit pump to adapter and 1-62 kit adapter to block.

was also cautioned to make sure when you drill block for adapter DONOT GO MORE THAN INSTRUCTED. will hit passages in block. was suggested to use a self centering bit, has small point at tip of bit, make sure you take the small point into account when measuring the drill depth
