Milodon windage tray on a 340 stroker

I dont use 4 bolt caps... but you should have no clearancing to do. The spacing if needed should be done with studs and double nuts, rather than a stack of washers and bolts. Like what the ARP studs do. If you have factory style bolts, that is why you need to space it. Just get .100" between the tray and anything that moves.
