Wheel cylinders

[WVscottsdale]

Has anyone had trouble getting wheel cylinders for their 3/4 & 1 ton trucks. All the auto part stores can't seem to figure it out. The ones I keep getting are too small and the bolt holes are to close to the hole for brake line. Thanks

What year? 1 ton or 3/4?

If it's a 1 ton, is it a dual?

Are you telling the parts place that it has 13" X 3" drums?

You show a 1977 1/2 ton - is this for a different truck?

I haven't had any trouble sourcing wheel cylinders for a 1986 K30 with single axle and 13 X 3 drums.
