67 twin turbo dart

After speaking with crower i am not sure that they make the lifter they told me that most companies hydraulic roller lifters are bought in from specialty industries
I have Johnson roller,Crower roller & Comp cams flat tappet & they all have identical parts inside valves, oil ,plates & spacers all the same
Probably shaving the bar is a safer option.
I filled the end of mine with hot glue then tapped the other to stop any grit getting into the roller the hot glue just pulls out when complete it doesnt enter the hole as the lifter is cold & the glue hardens quickly
If you get any grit into the roller bearing the lifter is toast
Does Kent have an idea how much meat is in the lifter area.
