Hy AZ59apacheguy, I'm not sure which "style" is correct, or identical to the o.e.m. part. To me they look like the same type of lifter manufactured by different companies. If I'm remembering correctly 235s don't have hollow pushrods so the hole in the top of the plunger which sends oil up the pushrod to the valve train is not required for the 235 application, hope that helps.
