Are you referring to the holes at the IP/bracket interface
or the bracket/block interface?
Sounds like the IP/bracket interface.
I am thinking I can either:1. Slot the holes in the bottom of the injection pump bracket such that it can slide further towards the flywheel side of the engine, concern being the bracket won't stay-put long term.
2. Add some sort of spacer(s)/washers between the injection pump body and the injection pump bracket, concern being this is too janky or not enough surface area connecting the two components. Writing this I recall having a sheet of stainless that I should measure the thickness of.
3. Machine the IP hub so it's thinner.
