What electric water pump is used with a Jesel belt drive?

This is my R3 with the Weber belt drive. The Smith Innovation adapter/spacers mate the R3 to the standard LA Meziere water pump. The spacers were a limited run so I bought 2 sets. So basically a whole bunch of “unobtanium”…. Weber belt drive, R3, SI spacers, W8… gotta love SBM. I have the gear and mounting plate for the front mount distributer. Just never went there…
