i dont know which model of howard that is.

youre going to have to make the plates yourself. every setback is different. they are easy to make. just make a template with cardboard and get a piece of aluminum plate and cut it out. take it to a machinist or even your favorite local boat shop if youre not comfortable doing it.

I believe that sir is a dominator bowl. It only has 8 nozzle bolts not 16 so it is not double drilled. The other side of the bowl i cant see but if it has 15 bolts its double drilled. Its one less bolt on the inside because of the water inlet. Matt

I be thinking it is a double drilled Dominator (doubled on the intake side....)

Agreed, have the same bowl. If it's got a smaller Inside diameter where the nozzle adapter is, then it's an older water lubricated dominator.

Nope, it's water lubricated. Don't EVER start it dry

I'm more inclined to think its an Agressor bowl, however all modern bowls with the exeption of Berkeley,some Legends and some Volvos (which are oil bath) have "greasable tail shaft bushings"  this would be/include  AT, Dom and Aggressor, energizer etc  , typically they (grease lubed) have a snap ring retained single or double seal and a zerk in the shaft plug at the rear . Some very early Dominators (Mar-bud) are "water lubed" , they have no seal and no tail shaft plug and no way to grease  Tom

BTW Water lubed bowls can easily be converted to Grease lube with a kit made by AT
