the gear on the left is the 8V gear from an intermediate shaft on a 93 B230FT. The gear on the right is the 16V cam gear from a B234F. The 16V gear is a few MM wider. If you place them on top of each other, you would see they have the exact same diameter and teeth spacing. So, if you convert, you will need to change to the crank pulley gear from a B234F and Use a cam gear on the Intermediate shaft.
